Latent variable models represent a useful tool for the analysis of complex\ndata when the constructs of interest are not observable. A problem related to\nthese models is that the integrals involved in the likelihood function cannot\nbe solved analytically. We propose a computational approach, referred to as\nDimension Reduction Method (DRM), that consists of a dimension reduction of the\nmultidimensional integral that makes the computation feasible in situations in\nwhich the quadrature based methods are not applicable. We discuss the\nadvantages of DRM compared with other existing approximation procedures in\nterms of both computational feasibility of the method and asymptotic properties\nof the resulting estimators.\n
