Resources for Computing and Evaluating Factor Scores

This web site offers a number of resources for computing and evaluating factor scores in the context of an exploratory factor analysis. The information herein is presented in a relatively nontechnical fashion and is directed primarily toward researchers and practitioners. Specific details regarding many of the ideas herein can be found in Grice (2001), a recent special issue of Multivariate Behavioral Research, or in one of many excellent articles published on factor scores.

Information Regarding Factor Scores
