Factor Analysis is a method for modeling observed variables, and their covariance structure, in terms of a smaller number of underlying unobservable (latent) “factors.” The factors typically are viewed as broad concepts or ideas that may describe an observed phenomenon. Another goal of factor analysis is to reduce the number of variables. The purpose of the factor analysis is usally to follow through to multiple linear regression (and therefore you shouldn't include the dependent variable in the factor analysis). Part 1 focuses on exploratory factor analysis (EFA). This seminar is the first part of a two-part seminar that introduces central concepts in factor analysis. Factor analysis is a statistical technique for identifying which underlying factors are measured by a (much larger) number of observed variables. This technique extracts maximum common variance from all variables and puts them into a common score.
Part 2 introduces confirmatory factor analysis (CFA). The analyst hopes to reduce the interpretation of a 200-question test to the study of 4 or 5 factors. Factor analysis has an infinite number of solutions. factor analysis. Factor analysis is a technique that is used to reduce a large number of variables into fewer numbers of factors. As an index of all variables, we can use this score for further analysis. Such “underlying factors” are often variables that are difficult to measure such as IQ, depression or extraversion. Although the implementation is in SPSS, the ideas carry over to any software program. For example, a basic desire of obtaining a certain social level might explain most consumption behavior. This is the type of result you want! A .8 is excellent (you’re hoping for a .8 or higher in order to continue…) BARTLETT’S TEST OF SPHERICITY is used to test the hypothesis that the correlation matrix is an identity matrix (all diagonal terms are one and all off-diagonal terms are zero). CFA attempts to confirm hypotheses and uses path analysis diagrams to represent variables and factors, whereas EFA tries to uncover complex patterns by exploring the dataset and testing predictions (Child, 2006).
One of the most subtle tasks in factor analysis is determining the appropriate number of factors.
The two main factor analysis techniques are Exploratory Factor Analysis (EFA) and Confirmatory Factor Analysis (CFA).
