1. 상관관계분석(Correlation analysis)이란?
상관관계(correlation): 두 변수간의 관계의 강도
상관관계 분석은 한 변수가 다른 변수와 상호관련성이 있는지 여부와, 관련성이 있다면 어느 정도의 관련성이 있는지를 분석하는 방법.
하나의 변수와 다른 변수와의 어떤 밀접한 관련성을 갖고 변화하는가 분
analysis
금 값은 모든 경제지표의 기준으로 현재 우리나라에서는 국내 금 시세와 국제 금 시세 두 가지 지표를 사용한다. 분석을 통하여 요동치는 미래의 금 시세를 예측하면 경제적인 이익을 얻을 수 있기 때문에 본 프로젝트를 시작하였다.
우리는 최대한 금 시세에 영향을 미칠 것 같은 데이터를 주
4. Regression analysis
4-1 Tourism destination image depending on PPL effect
We analyzed that PPL give what kind of effect on to Cognitive, Emotional tourism destination image. In other words, we took linear regression analysis to know the Cognitive, Emotional tourism destination image depending on PPL effect. Through the variable calculation, we got the mean of PPL effect. We set this to
users and correlated them to the satisfaction of the phone and phone’s performance. Research here is done in a noncontrived setting with non interference with the user’s activities.
Unit of analysis: individuals
We want to know the relationship between the satisfaction of the two phone’s user and two phone’s satisfaction. For this purpose, data will have to be collected from each
indoor environmental score of buildings and occupants' satisfaction, and research about the correlation between criteria and satisfaction. Second, we will compare and analyze between satisfaction of LEED buildings and non LEED building’s, and research effectiveness of LEED certification. As a result, we will suggest development to indoor environment of green office buildings for more human.

※ Survival Analysis
; Deals with analysis of data that have "time to an event".
※ Survival time
; Time until an event occurs.
※ Event
; a. relapse of a disease
b. death
c. response to a treatment
; Economical,
To obtain answers quickly because the cas
correlation is 0, they have Collinearity not at all. Especially, relationship among 3 or more variables is called multicollinearity.
Tolerance limit means a part that a factor variable is not explained by other variables. In other words, if tolerance limit is small, multicollearity is high. In this analysis tolerance limit is 1 that is biggest number so we don't need to interpretate it.
