On Inclusion of Covariates for Class Enumeration of Growth Mixture Models
Li, Libo; Hser, Yih-Ing
Multivariate Behavioral Research, v46 n2 p266-302 2011
In this article, we directly question the common practice in growth mixture model (GMM) applications that exclusively rely on the fitting model without covariates for GMM class enumeration. We provide theoretical and simulation evidence to demonstrate that exclusion of covariates from GMM class enumeration could be problematic in many cases. Based on our findings, we provide recommendations for examining the class enumeration by the fitting model without covariates and discuss the potential of covariate inclusion as a remedy for the weakness of GMM class enumeration without including covariates. A real example on the development of children's cumulative exposure to risk factors for adolescent substance use is provided to illustrate our methodological developments. (Contains 1 footnote, 7 tables, and 15 figures.)
