Abstract
This paper discusses the impact of population heterogeneity on factor analysis under the homogeneity assumption and potential biases resulting from aggregation. An illustration using the Holzinger-Swineford Mental Abilities data shows that the factor mixture model relaxes factor analysis specification taking population heterogeneity and potential outliers into account.
