Analysis of Multitrait-Multioccasion Data: Additive versus Multiplicative Models

The aim of this article is to address the question of whether empirical multitraitmultioccasion data conform more closely to multiplicative models than to additive models. Four additive models and two versions of the multiplicative Direct Product (DP) model (Browne, 1984) are tested. A set of 21 multitrait-multioccasion matrices is analyzed by means of LISREL 8 (Joreskog & Sorbom, 1993). The results obtained across different models are evaluated...
