Definition factor analysis
WebExploratory factor analysis. In multivariate statistics, exploratory factor analysis ( EFA) is a statistical method used to uncover the underlying structure of a relatively large set of variables. EFA is a technique within factor analysis whose overarching goal is to identify the underlying relationships between measured variables. [1] WebFactor analysis includes both component analysis and common factor analysis. More than other statistical techniques, factor analysis has suffered from confusion concerning its very purpose. ... The major reason for this is the eigenvalue's definition as a weighted sum of squared correlations. However, it also turns out that the actual variance ...
