Abstract:

This study is concerned with approximated penalized maximum likelihood (APML) for exploratory factor analysis. A simulation study is conducted to investigate the performance of the APML estimator. The APML estimator was found to frequently contain the correct loading structure and improve the varimax rotation if the loading matrix is not perfect simple. With a proper choice of the penalty term and a tuning parameter selection method, APML generally produces a lower mean squared error for the factor loadings, the covariance (or correlation) matrix and the Thompson factor scores.
