An extended forward search algorithm to detect latent dimensionality, population heterogeneity and measurement invariance in latent variable models



Abstract

In this paper, we extend the forward search algorithm developed initially to detect outliers in regression models and later in factor models for continuous and binary data to address questions of latent dimensionality, population heterogeneity and measurement invariance. We present simulation studies and real examples that justify the successful use of the algorithm in all those cases. The FS algorithm can be used in combination with goodness-of-fit test and fit measures and in some cases to overcome their limitations.
