The inside story of MIT and Aaron Swartz: More than a year after Swartz killed himself rather than face prosecution, questions about MIT’s handling of the hacking case persist

Requiem for a Dream: Aaron Swartz was brilliant and beloved. But the people who knew him best saw a darker side. - by LARISSA MACFARQUHAR at Newyorker</description>

        <description>Using absolute value of deviation score as an alternative of standard deviation

Q: 왜 차이값을 (deviation score) 제곱하여 더한 값의 평균 (즉, 분산 Variance) 을 사용하나요? 차이값의 절대값을 더한 값의 평균을 사용하는 것이 더 직관적이지 않나요? $ \text{absolute value of deviation score} = \displaystyle \frac {\sum |(X_i-\mu)| }{N} $\begin{eqnarray*}
\text{SS} &amp; = &amp; \small{\sum} (X_i-\overline{X})^2  \\
  &amp; = &amp; \text{. . . .}  \\
  &amp; = &amp; {\sum} X_i^2 - \frac{({\sum} {X_i)^2}}{n}

        <description>Adaptive Structuration Theory

From the Univ. Twente in Netherland

History and Orientation
Adaptive Structuration Theory is based on Anthony Giddens&#039; structuration theory. This theory is formulated as “the production and reproduction of the social systems through members’ use of rules and resources in interaction”. DeSanctis and Poole adapted Giddens&#039; theory to study the interaction of groups and organizations with information technology, and called it Adaptive Structuration Theory.

        <description>AIC는 모델의 적합도와 예측 변인의 갯수가 (파라미터의 갯수) 적절한지를 보는 지표이다. 예측변인이 필요이상으로 많다면 AIC지수가 높아지게 되어 적절한 모델이 아님을 알려준다. 이것은 anova 펑션을 이용하여 중첩된 두 회귀분석의 F값을 비교하는 방법과 비슷하다고 보면 된다.</description>

전화기를 발명한 Alexander Graham Bell과 그의 장인인 Gardiner Hubbard가 1877년 Ameriacan Bell Telephone Company라는 회사를 설립하였다. 이들은 1885년에 American Telephone and Telegram Company라는 회사를 후속 설립하였는데, 나중에는 후자가 전자를 흡수통합하였다. AT&amp;T로 알려진 이 회사는 미국 전화산업의 독점적인 전화회사로 성장하다가 1981년에 반독점법에 의해서 여러개의 회사로 쪼개지게 된다 (MCI, Sprint 등)…</description>

사회과학은 자연과학과 마찬가지로 법칙정립적 (monotonic) 인과관계를 추정하는 것이지만, 사회과학에서의 인과관계는 자연과학과에서의 그것과는 다른 성격을 갖는다. 대표적으로 법칙정립적 인과관계가 곧 완전한 인과관계를 이야기 하지 않는다. 즉, 사회과학에서의 인과관계는 불완전하다. $ \forall $</description>

소개

Central Limit Theorem (CLT) 이란:: 평균이 $ \mu$ , 그리고 표준편차( $ s$ )가 $ \sigma$ 인 모든 종류의 모집단에서, 샘플 숫자를 $ n$ 으로 하여 샘플평균을 분포시키면, 그 분포는 정규분포(normal distribution)를 이루며, 그 분포의 평균(mean, $ \mu_{\overline{x}}$$ \mu$$ s_{\overline{x}}$$ \sigma / \sqrt{n}$$\mu_{\overline{X}} = E[\overline{X}] = \mu $$\sigma_{\overline{X}} = Var[\overline{X}] = \dfrac{\sigma^{2}}{n}$$\te…</description>

COGNITIVE CONSEQUENCES OF FORCED COMPLIANCE
Leon Festinger &amp; James M. Carlsmith (1959)

First published in Journal of Abnormal and Social Psychology, 58, 203-210.

----------

What happens to a person&#039;s private opinion if he is forced to do or say something contrary to that opinion? Only recently has there been any experimental work related to this question. Two studies reported by Janis and King (1954; 1956) clearly showed that, at least under some conditions, the private opinion ch…</description>

        <description>Cognitive Dissonance Theory

출처: &lt;http://www.age-of-the-sage.org/psychology/cognitive_dissonance.html&gt;

Cognitive Dissonance theory was first developed by Leon Festinger in 1956 after the publication of a book, When Prophecy Fails, written with co-authors Henry W. Riecken and Stanley Schachter, to explain how members of a UFO doomsday cult increased their commitment to the cult when a prophesied destruction of the Earth did not happen. The cult&#039;s leader, a certain Mrs Keech, had, seemingly, been…</description>

by Olson, Mancur
[The logic of collective action: Public goods and the theory of groups] by Mancur Olson

조직, 그룹,  사회, 국가의 이익 vs. 자기 개인의 이익 
개인은 집단에게서 무엇인가를 얻고자(얻을 수 있으므로) 자진하여 소속됨 
개인은 공공이익(선)을 위해서 비용을 지불하고 공공이익이 분사하는 개인이익을 누리려고 함 
집단이 커질 수록 집단이 주는 이익의 배분이 불분명해지고, 자신이 지불하는 비용의 사용이 불명확해 짐 
창출된 공공이익이 불특정 다수에게 이익을 줄 때 (이익의 배타성이 없어질 때) 
자신의 비용이 절대적 필요가 아님을 인지하고 무임승차(free riding)를 시도함…</description>

        <description>Conceptualization

광범위한 연구문제를 좀더 구체화하기 위한 작업으로 conceptualization이 있다. &#039;Concept(개념)를 만드는 과정&#039;으로 생각할 수 있는데, 이는 곧 컴퓨터를 이용한 커뮤니케이션이 무엇을 의미하는 지에 대해서 고찰하고, 이를 구체화하는 것이다. 컴퓨터를 이용한 커뮤니케이션으로 이매일을 이용한 것에 한정지어 생각을 해 볼 수 있을 것이고, 특히 이매일이 부모와의 커뮤니케이션에 어떻게 사용되는 지에 대해서 궁금할 수 있을 것이다.…</description>

Covariance

\begin{eqnarray*}
Cov[X, Y] &amp; = &amp; E[(X-EX)(Y-EY)] \\
&amp; = &amp; E[XY] - (EX)(EY) \\
\end{eqnarray*}

\begin{eqnarray}
E[(X−EX)(Y−EY)]  \nonumber \\
&amp; = &amp; E[XY−X(EY)−(EX)Y+(EX)(EY)] \\
&amp; = &amp; E[XY]−(EX)(EY)−(EX)(EY)+(EX)(EY) \\
&amp; = &amp; E[XY]−(EX)(EY)\\
\end{eqnarray}

위 $[1]$에서 $[2]$가 되는 이유는 $E[X], E[Y]$ 가 상수이기 때문. 가령, 
\begin{eqnarray*}
E[X*2] &amp; = &amp; 2*E[X] 
\end{eqnarray*}
위처럼 $ E[X] = \mu$ 로 보면
\begin{eqnarray*}
E[X*\mu] &amp; = &amp; \mu*E[X] \\
&amp; = &amp; E[X]E[X]
\end{eqnarray*}

어떤 모집단에서 샘플을 취하였다면, 그 샘플의 평균과 분산 값은 그 모집단의, 그것들과 일치할 수는 없지만, 비슷해야 할 것이다. 따라서, 흔히 우리는 샘플의 평균과 분산값을 가지고 모집단의 그것을 추정하게 된다. 모집단의 분산을 구하는 공식은 아래와 같다 (\begin{equation*} 
\sigma^2 = \frac {\displaystyle \sum_{i=1}^N {(X_i-\mu)}^2}{N}
\end{equation*}\begin{equation*}

그의 생애

[&quot;As We May Think”]더글러스 엥겔바트(Douglas C. Engelbart)는 1925년 1월 30일 오리건 주에서 태어났다. 그는 노르웨이, 스웨덴계 미국인 발명가이다. 그는 특히 컴퓨터 마우스의 발명자로 유명하다. 또한 그래픽 사용자 인터페이스, 하이퍼텍스트, 네트워크 컴퓨터 등 인간과 컴퓨터 상호 작용 분야의 선구자이다. 1948년 오레건 주립대학교에서 전기공학 학사학위를 받았고, 1953년 UC 버클리에서 공학 석사학위를 받았다. 1955년에는 동 대학에서 박사학위를 받았다. 제2차 세계대전 직후에는 필리핀에서 레이더 기술병으로 해군에 복무하느라 2년간 휴학했다. 필리핀의 무선전기 기사로 해군에 복무하던 시절, 배니버 부시 Vannevar Bush가 쓴 &#039;우리가 생각하듯 (As We May Think)&#039;란 글에서 큰 영감을 받는다. 전쟁이 끝나고, 영감을 실현시키기 위해 UC 버클리에서 공부를 계…</description>

? __Elaboration Likelihood Model (ELM)__
: posits two possible routes or methods of influence: (1) centrally routed messages, and (2) peripherally routed messages. Each route targets a different audience. ELM focuses on the importance of understanding audience members before creating a persuasive message.
: ELM depicts persuasion as a process in which the success of influence depends on the way the receivers make sense of the message.</description>

        <description>Why n-1

문제.

우리는 모집단의 (population) 평균값을 알고 있다면 샘플의 분산값을 다음과 같이 구할 수 있다. 그리고, 이것을 모집단의 분산값으로 추정할 수 있다. 

\begin{eqnarray*}
\widehat{\sigma^2} = \dfrac {\displaystyle\sum_{i=1}^{n}{(X_{i}-\mu)}} {n} 
\end{eqnarray*}

그러나, 현재 우리가 가지고 있는 것은 샘플 밖에 없다. 즉, 모집단의 평균은 알지 못하는 상태이기에 모집단 분산을 추정하는 계산에 사용할 수 없다. 따라서 샘플의 평균을 사용한다. 그런데, 샘플의 평균을 사용할 때는 분모에 N 대신에 n-1을 사용해야 한다. 왜 n-1을 사용하는것이 모집단의 분산값 추정에 도움이 되는가가 문제이다. \begin{eqnarray*}
\widehat{\sigma^2} \neq \frac {\displaystyle\sum_{i=1}^{n}{(X_{i}-\overline{X}…</description>

Factorial ANOVA

t-test와 ANOVA의 섹션까지 다룬것은 모두 하나의 독립변인(Independent Variable)과 하나의 종속변인(Dependent Variable) 간의 관계에 대한 규명을 하는 것이었다. 

실제 연구를 하는 경우 이와 같이 하나씩의 독립변인과 종속변인으로 이루어진 검증을 하기보다는 여러가지 다른 원인을 종합적으로 살펴보는 때가 많다. 즉, 연구자는 실험참가자의 행동이나 반응으로 나타나는 종속변인의 원인을 하나의 독립변인이 아닌 여러가지 (대개는 2가지) 독립변인을 놓고 살펴본다는 것이다.$\overline{X_{30_{\\\%}}} = ? $$ \overline{X_{70_{\\\%}}} = ? $$ \overline{X_{24^{c}}} = ? $$ \overline{X_{29^{c}}} = ? $$ \overline{X_{34^{c}}} = ? $$$F = \frac{\te…</description>

I saw that the world, the social system that encouraged people to cooperate was being replaced by one in which cooperation was called piracy, and I decided that all I could possibly get by participating in that was money, and that just money was not enough to live for.

        <description>Q. 어떤 자격증 시험의 합격율은 15%라고 한다. A학생이 이 자격증을 3번 이상 시험을 쳐서 따게 되는 확률은?
A. 3번 이상 시험을 쳐서 합격증을 따는 것은 3번째 응시에서 따게되는 경우, 4번째 응시에서, 5번째 응시에서, . . . . 자격증을 따게 되는 경우를 모두 포함하는 것이므로 한계가 없는 기하분포에서는 (geometric distribution) 구할 수가 없다. 그러나, 전체 확률을 1로 놓고 (100%) 그 중에서 첫번째 응시 성공, 두번째 응시 성공을 제외하면 (이 때 자격증을 따게 되면 3번까지 갈 필요가 없게 되므로), 3번 이상의 응시로 자격증을 따는 확률을 구하는 것이 된다. 따라서

 호손연구는 1924년부터 실행된 공장환경에서의 생산성 향상에 관한 연구였다. 당시는 산업화가 본격화되면서 경영학과 관련된 분야에 많은 학문적 관심이 쏠렸다. 이 연구는 Western Electric Company라는 회사가 시카고 소재의 호손이라 불리는 공장에서 생산성을 연구하면서 시작되었다. 이 회사는 1869년에 Gray and Barton이라는 이름의 회사로 만들어져 전화관련산업의 공급회사로 출발하였다. 삼년 후에 설립자의 이름을 딴 회사에서 Western Electric Manufacturing Company라고 개명을 하였고, 탄탄한 매출성과를 내다가 1881년에 당시 전화회사로는 가장 큰 회사였던…</description>

        <description>Homoscedasticity

 

Residual 이 predicted DV 점수에 패턴없이 퍼져 있는 상태를 말하는데, 이는 다시 말하면, residual의 분산 정도가 predicted value의 변화에 따라서 일정하게 나타난다는 뜻이다. 이러한 무패턴을 homoscedasticity라고 하고 반대의 경우를 heteroscedasticity라고 한다.</description>

        <description>Hyperpersonal CMC

The hyperpersonal model of CMC (Walther, 1996) proposes a set of concurrent theoretically based processes to explain how CMC may facilitate impressions and relationships online that exceed the desirability and intimacy that occur in parallel off-line interactions. The model follows four common components of the communication process to address how CMC may affect cognitive and communication processes relating to message construction and reception: (1) effects due to receiver pr…</description>

연구문제와는 약간 다르지만 비슷한 성격을 갖는 것으로 가설이 (hypothesis) 있다. 연구문제는 두 개념 간의 관계에 대한 질문으로 만들어지지만, 가설은 이 관계에 대한 답을 선언하는 형식으로 만들어 진다. 좀 복잡하게 말하면, 가설은 $ \bar{X}_{self} &lt; \bar{X}_{others} $$ \bar{X}_{self}-\bar{X}_{local} &lt; \bar{X}_{self} - \bar{X}_{nation} $$ \bar{X}_{\text{the third person effect not perceived}} &lt; \bar{X}_{\text{perceived}} $$ \bar{X}_{\text{non perceiver}} &gt; \bar{X}_{\text{negative perceiver}} $…</description>

가설에는 차이와 관련을 나타내는 것이 있다고 하였다 (Hypothesis 참조). 가설에 나타나는 IV 와 DV 가 어떻게 측정(measure)이 되었는가에 따라서 차이와 관련의 가설로 나누게 된다. 아래 가설들은 각각의 변인(독립, 종속변인)들이 어떻게 측정되었는가에 따라서 예를 들기 위해 만들어진 것이다. $ \overline{X}_\text{male}$$ \overline{X}_\text{female}$$ 74.88 $$ 67.54 $$ 74.88 \ne 67.54 $$\displaystyle  \text{H(0): } \overline{X}_{\text{student with wiki}} = \mu \;\;\; \text{where } \mu = 50 $$ \text{H(0):} $$ \text{H(0):} $$\displaystyle  \text{H(0): } \overline{X}_{\text{student wit…</description>

        <description>T-TEST

About T-test:

I have thought a proper way to make the t-test accessible; but, I figured out that it is not helpful to skip z-score and z-test. Before I tell any further, I&#039;d like to mention that the t-test and z-test are virtually the same. Some differences are discussed later.$\sigma_{\overline{X}} = \frac{\sigma}{\sqrt{N}} = 2; $$\mu_{\overline{X}} = \mu$$Z = \frac{\overline{X} - \mu}{\sigma_{\overline{X}}} = \frac{(105-100)}{2}$$Z = \frac{\overline{X_1} - \overline{X_2}}{\sigma_{diff…</description>

개인이나 작은 단위를 보고 큰 단위를 판단하는 것을 말한다. 개인을 보고 전체화 하는 것을 흔히 스테레오타이핑이라고 하는데, 이를 말한다. 미국선생님이 자신의 수업에서 인도학생이 수학을 잘하는 것을 보고, 모든 인도학생이 수학을 잘할 것이라고 판단하는 것이 이에 해당하겠다. exceptional fallacy라고도 한다.</description>

Inferential이란 (추정) 샘플의 특성을 (statistics) 가지고 모집단의 특성을 (parameters) 추정하는 것과 같은 작업을 말한다. 소의 젖 생산량이 하루에 얼마인지를 알기 위해서 전수조사를 (enumeration) 할 수는 없으므로 어느 정도 규모의 데이터를 수집하여 이를 근거로 모집단이 어떤 결과일지를 추론하는 것이 예이다. 추론이 정확하기 위해서는</description>

마할라노비스 거리란 각각의 케이스가 여러가지 변인(variables) 중심값 (평균값, mean) 들로 이루어진 중심 (centroid) 에 대해서 갖는 거리를 말한다. 개념적으로 살펴보면, 여러변인을 동시에 이용하여 살펴보는 테스트 (multivariate) 경우에 각각의 중심값을 중앙에 교차시켜 케이스 값들을 나열해보면 일종의 군집을 이루게 되는데, Mahalanobis distance는 특정 케이스의 값이 여기서 심하게 벗어났는가를 보기 위한 거리값이다.  $\chi^2$$\chi^2$$h_{ii}$$$ \text{Mahalanobis distance} = (N-1)(\frac{h_{ii}-1}{N}) $$$$ h_{ii} = \frac{\text{Mahalanobis distance}}{N-1} + \frac{1}{N} $$…</description>

        <description>MS-DOS (Disk Operating System)

운영체제 (OS: Operating System)란

컴퓨터 시스템을 제어하고 관리하는 소프트웨어를 운영체제(OS:operating system)라고 한다. 이 운영체제는 컴퓨터 시스템이 가동하기 시작하면 주기억장치 가 이를 읽어 시스템을 관리하게 되지만, 기본적으로는 디스크나 자기 테이프 등의 보조기억장치에 저장되어 있다. 운영체제를 어떤 보조 기억장치에 저장하고, 어떤 보조기억장치를 중심으로 하여 컴퓨터 시스템을 관리하는가에 따라 운영체제를 분류하거나 명명하고 있다. DOS는 디스크에 운영체 제를 저장하고 있으며, 디스크를 중심으로 시스템을 관리한다. 과거에는 자기 테이프에 운영체제를 저장하고 이를 중심으로 시스템을 관리하였으나, 현재는 대부 분이 디스크를 중심으로 관리하고 있기 때문에 거의 모든 운영체제를 DOS라 불러도 무방하다고 볼 수 있다. DOS라는 용어를 상품명으 로 사용하기도 하였는데 가장 유명한 것은 마이크로…</description>

        <description>Multicollinearity and Singularity

변인들 간의 상관관계가 극한 정도로 이루어질 때 multicollinearity가 있다고 한다. 예를 들어 IQ score와 수학점수는 상당한 상관관계에 있을 것이다. 이 두 변인은 서로 비숫한 대상(현상)을 측정한 것이기 때문이다. 이 두 변인이 독립변인으로 regression과 같은 test에 사용된다면, 동일한 현상에 대한 설명력을 나눠가지려고 하기때문에 문제를 일으키게 된다.…</description>

See also Regression 혹은 단순회귀 

Simple regression과 (단순회귀) mutiple regression (다중회귀) 분석은 하나의 종속변인과 다른 독립변인들(복수에 주의) 간의 관계에 대해서 살펴볼 때 사용되는 보편적인 분석방법 중의 하나이다. correlation이나 regression 이라는 용어는 보통 뚜렷한 의미차이를 두지 않고 혼용되는 경향이 많은데, 궂이 가리자면, regression은 예측 (prediction)을 하는데 많이 쓰이고, correlation은 변인간의 관계를 알아보는데 더 많이 쓰인다. $$Y = a + bX$$$\overline{Y}=8$$SS_{total} = 30$$\overline{Y}$$\overline{Y}=8$$SS_{total} = 30$$$\hat{Y} = 6.399103 + (-0.544727) \text{fammember} + (0.011841) \text{income…</description>

스티브 잡스

NeXT 사를 말하기 전 스티브잡스라는 인물을 빼놓을 수 없다. IT역사의 기념비적 혁명을 두 번( 애플Ⅱ-개인용 PC 혁명, 아이폰-스마트폰 혁명 )이나 일으킨 희대의 천재인 그가 바로 NeXT 사를 설립한 장본인이기 때문이다. 애플에서의 갈등으로 인한 퇴사 후, 다시 애플로 복귀하여 성공하기까지 NeXT 사의 CEO로 역임하며, 완성형 CEO로 발전해나갔기 때문에, 스티브 잡스 인생에 있어 NeXT와 함께했던 경험이 가장 소중한 시간으로 여겨진다. 후에 애플의 고문과 임시 최고 경영자를 거쳐 자리에 오르게 된다.…</description>

좌우대칭이며 asymtotic한 분포를 이루는 것을 정상분포라고 한다. 수학적으로 정상분포는 아래와 같이 정의된다.

        <description>다원적 무지

다수의 사람들이 소수의견을 다수인 것처럼 인지하고 그렇게 행동하는 현상을 말한다. 박정순의 오래전 연구에 의하면 광주와 대구 지역의 사람들에게 자신이 다른 지역(대구-광주, 광주-대구)의 사람들을 얼마나 싫어하는지를 조사하고, 자기 지역 사람들이 얼마나 다른 지역사람들을 싫어하는지와 다른 지역의 사람들이 자기 지역의 사람들을 얼마나 싫어할 것인지를 조사하여 보았다. 그 결과 박정순은 43.6%의 대구지역 사람들이 호남지역 사람들을 싫어한다고 나타난 반면 84% 사람들이 광주지역 사람들을 나쁘게 생각할 것이라고 인지함을 보였다. 또한 광주지역 사람들의 86%가 대구지역 사람들을 싫어 할 것이라고 대답하였지만, 실제 광주지역 사람들은 35%만이 대구지역 사람들을 나쁘게 생각한다고 대답하였다.…</description>

Difference between PCA and FA

	*  Both are data reduction techniques — they allow you to capture the variance in variables in a smaller set.
	*  Both are usually run in stat software using the same procedure, and the output looks pretty much the same.
	*  The steps you take to run them are the same-extraction, interpretation, rotation, choosing the number of factors or components.</description>

두 변인 간의 상관관계가 완전하다면 (r=1.0 혹은 r=-1.0) 변인 간의 상관관계에 의한 그래프는 아래와 같을 것이다.
$$Y = a + bX $$
여기서, a는 절편이라고 (intercept) 하고, b는 기울기라고 (slope) 한다. 즉, 완벽한 상관관계일 때 나타나는 관계 그래프는 일차 방정식의 형태를 띄게 된다 (따라서 이를 linear한 관계라고 한다).$$\hat Y = a + bX $$$$\hat Y = 5 + 2 X $$$\hat Y$$X_i$$Y_i$$\hat Y$$Y_i$$\hat Y$$Y_i$$(Y_i - \hat Y)$\begin{eqnarray*}

신뢰도란 반복적으로 동일결과가 나오는가에 관한 문제이다 (반복성, repeatition). 내 몸무게를 잴 때 사용하는 저울이 어떤 때에는 100kg을 가르키고, 어떤 때는 65kg을 가르키는 등, 매번 잴 때마도 틀려진다면 반복성이 없는 저울이므로 신뢰도가 없다고 할 수 있다. 그러나 신뢰도가 정확도를 의미하는 것은 아니다. 만약 나의 몸무게가 65kg인데, 어느 한 저울이 매번 지속적으로 70kg을 가르킨다면 이 저울의 신뢰도는 문제가 없지만 정확도에는 문제가 있다고 하겠다.

        <description>Introduction. Science, natural science, social science, humanity

이 책은 사회과학을 하는 사람이면 한 번쯤 거쳐야 할 조사방법론과 커뮤니케이션 이론에 대해서 다루고 있다. 사회과학분야의 조사방법론을 다루기에 앞서서 과학이라는 단어가 여러분에게 어떤 것을 던지는지 생각해 보았으면 한다. 과학이 무엇인가라는 따분한 정의에 대해서 이야기 하려는 것이 아니라, 단순히 과학이라는 단어로 인해 연상되는 것이 무엇인가에 대해서 묻는 것이다. 기초교육 기간 중에 바퀴의 시작, 피타고라스의 정리, 화성학, 점성학,  기하학 등을 배우기는 하지만 이런 것들이 과학과 연상되기 보다는 뉴튼의 만류인력의 법칙, 갈릴레오의 발견, 아인슈타인의 상대성 원리 등등이 우리에게 보다 친근한 과학의 이미지이다. 넓은 의미에서의 과학은 인간의 역사와 함께 서서히 발전해 온것이 사실이지만, 현대인들이 생각하는 과학은 일반적으로 근대(modern)라는 단어와 함께 인류…</description>

Logistic regression에서는 linear regression 에서 사용하는 R^2 값을 구할 수는 없다. 따라서 이에 대응하는 개념을 적용하는 여러가지 방법이 개발되어 사용되고 있는데 그 중에서 가장 많이 쓰이는 방법이 McFadden&#039;s pseudo R square 이다. \begin{align*}
R^2 = &amp; \frac {SS_{regression}} {SS_{total}} \\
    = &amp; \frac {SS_{total} - SS_{residual}} {SS_{total}} \\

        <description>Skewness (왜도)는 자료 (데이터)의 분포가 한 방향을 편향된 정도를 말한다. 

$$
S_k = 3(\bar{X}-Median) / s
$$

$S_k$ = skewness 왜도계수
$\bar{X}$ = 표본의 평균
$Median$ = Median (중앙값)
$s$ = 표본의 표준편차

양의 왜도: 자료가 오른 쪽으로 길게 뻗어 있는 분포를 의미한다. 
음의 왜도: 자료가 왼 쪽으로 길게 뻗어 있는 분포를 의미한다.</description>

        <description>Social Presence Theory

사회적 실재감 이론은 Short, Williams, Christie에 의해서 주창된 이론으로 커뮤니케이션 상대방과의 물리적인 거리와 심리적인 거리 간의 차이를 지적하는 이론이라고 할 수 있다. 전화와 편지라는 매체(medium)을 비교할 때, 전화는 편지에 비해 상대방의 존재감이 현저하게 강하다는 것이 핵심적인 생각이다.</description>

        <description>허위관계

상관관계나 영향력 관계가 없는 두 개념 간의 관계에 대한 설명을 허위관계에 대한 설명이라고 한다. 아이스크림의 판매량과 익사률 간에 상관관계가 높은 이유는 둘 다 온도가 관련되어 있기 때문이지, 이 두 개념이 서로 관련이 있기 때문은 아니다. 즉, 날씨가 더울 수록 물놀이나 수영 등이 많아질 것이고 이로 인한 사고가 많아지기 때문에 익사율이 높아지는 것이지, 아이스크림 판매량이 익사에 영향을 주는 것은 아니다. 마을(행정)단위를 관찰할 때 그 마을의 당나귀가 많을 수록 박사학위율이 낮아지는 것은 두 개념 간에 상관관계가 있어서가 아니라, 도시와 농촌이라는 환경이 당나귀의 숫자와 박사학위율에 모두 영향을 미치기 때문이다. 도시환경일 수록 당나귀의 숫자가 적을 것이고 박사학위소지자는 많아질 것이다. 펠리컨이 많은 지역일 수록 출산율이 높다. 그 이유는 펠리컨이 아이를 배달해 주기 때문이다라고 생각하는 것 또한 허위관계에 기초한 논리이다. 펠리컨의 숫자가 적은 지역은 도시 환경…</description>

        <description>표준편차, kr

Standard Deviation(표준편차)는 variance(분산)값을 square root한 값을 말한다. 애초에 분산의 정도를 구하기 위해서 deviation score를 제곱한 값을 사용하였으므로 이에 다시 제곱근을 한 것이다. 
\begin{eqnarray*}
\sigma^2 &amp; = &amp; \frac{SS}{N} = \frac{SS}{N-1} \\

변인이 수치로 측정된 경우의 표준오차란 (standard error) 모집단에서 샘플을 취했을 때 그 샘플의 평균이 모집단의 평균에서 얼마나 떨어져서 나타날까를 (평균에서부터의 랜덤 에러) 나타내주는 지표로 샘플평균집합의 표준편차를 (standard deviation of sample means) 말한다 (</description>

 Noxema with Farrah Fawcett and Joe Namath. 
It&#039;s possible GoDaddy learned about double entendres and sexy Super Bowl spots from Noxema, which was using it as a ploy way back in 1973. This commercial is noteworthy because it paired America&#039;s favorite quarterback at the time with its favorite pinup. What the vintage spot lacks in taste (a lot) it makes up in star power.</description>

테일러 급수 
Taylor&#039;s series of $e^x$
일반화된 설명은 너무 복잡하고 아래와 같이 생각해보자

$e^x = \displaystyle \sum_{k=0}^\infty {\frac{x^k}{k!}}$ 이라고 하면

\begin{align*}
e^x &amp; = \displaystyle \sum_{k=0}^\infty {\frac{x^k}{k!}} \\
&amp; = 1 + x + \frac{x^2}{2!} + \frac{x^3}{3!} + \frac{x^4}{4!} + . . .  \\
\end{align*}

$x=2$ 일 때
\begin{align}
e^2 &amp; = &amp; 1 + 2 + \frac{2^2}{2!} + \frac{2^3}{3!} + \frac{2^4}{4!} + \frac{2^5}{5!} +  . . .  \\

 Ethnographic study - Situation-based approach. Lord Humphrey는 공중화장실에서 일어나는 동성애자들 간의 관계를 관찰하였다. “Tea-rooming”이란 이런 공공 화장실에서 동성애자들을 만나는 것을 의미하는 슬랭이었다. 그들의 사회적인 단서와 큐등을 관찰하여 험프리는 이 과정에 보통 3인이 관련되는 것을 알아내었는데, 제3의 인물은 동성애자의 애정행각을 망봐주는 사람이었다 (watchqueen).…</description>

        <description>SIDE

개인의 아디덴티티가 소속집단이나 사회적범주에 따라서 다르게 나타나는 것을 설명하는 이론으로, 소속집단의 아이덴티티가 개인의 아이덴티티보다 서로 우위를 점하게 되는 과정을 설명한다. 또한, CMC와 같은 익명성(cues-filtered-out)을 보장하는 환경에서의 개인의  ID와 집단의 ID가 어떻게 작용하는지를 설명한다.</description>

        <description>제3자 효과

사람들이 매스미디어가 자신을 중심으로 사회적 거리가 먼 사람들에게 더 많은 영향력을 행사할 것이라고 생각하는 경향을 일컫는다. 주로 부정적인 메시지나 효과와 관련하여 이런 경향이 두드러진다고 하며, 반대로 긍정적이거나 친사회적인 메시지나 내용에는 역작용이 일어난다고 주장되기도 한다.</description>

Identifying variables

Please focus on dependent and independent variable first. You should be able to distinguish them. This is a good material to see if you understand the textbook alright.



Dependent

A variable assumed to be dependent or be affected or caused by another (called the independent variable). If A is the result of the function of B, A is dependent variable. We can think A is a dependent variable because A is caused by the B(&#039;s fun…</description>

        <description>Usenet

. . . . Today there are great forces battling to structure and control the information superhighway, and it is invaluable that the Internet and Usenet exist as working models. Without them it would be quite easy to argue that the information superhighway should have a top-down hierarchical command and control structure.

Warranting pertains to the perceived legitimacy and validity of information about another person that one may receive or observe online. Individuals often come to learn quite a lot about each other through discussions in topical online discussion groups or through online role-playing games (see Parks…</description>
