| contents | Previous research has shown that ignoring individual differences of factor loadings in conventional factor models may reduce the determinacy of factor score predictors. Therefore, the aim of the present study is to propose a heterogeneous regression factor score with larger determinacy than the conventional regression factor score when individuals have different factor loadings. First, a method for the estimation of individual loadings is proposed. The individual loading estimates are used to compute the heterogeneity-based regression factor score predictor. Then, a binomial test for loading heterogeneity of a factor is recommended to compute the heterogeneity-based regression factor score predictor only when the test is significant. Otherwise, the conventional regression factor score predictor should be used. A simulation study reveals that the heterogeneity-based regression factor score predictor has larger determinacy than the conventional regression factor score predictor in populations with substantial loading heterogeneity. An empirical example based on subsamples drawn randomly from a large sample of Big Five Markers indicates that the determinacy can be improved for the factor emotional stability when the heterogeneity-based regression factor score is computed. |
