Rabe-Hesketh, Sophia; Skrondal, Anders; Pickles, Andrew – Psychometrika, 2004
A unifying framework for generalized multilevel structural equation modeling is introduced. The models in the framework, called generalized linear latent and mixed models (GLLAMM), combine features of generalized linear mixed models (GLMM) and structural equation models (SEM) and consist of a response model and a structural model for the latent…
