Regression Analysis of Multivariate Binary Response Variables Using Rasch‐Type Models and Finite‐Mixture Methods

TLDR: This work examines the relationship between this model and several other models, gives a tractable formulation of the likelihood function and likelihood equations, presents an algorithm for maximum-likelihood estimation, and analyze marginal and conditional latent structures.

Abstract: A model is considered for the regression analysis of multivariate binary data such as repeated-measures data (for example, panel data) or multiple-indicators with measures of some underlying characteristic such as attitude or ability (for example, surveys or tests). The model is related to the usual Rasch model, the usual latent-class model, and other familiar models such as logistic regression. In addition to a regression specification, the model includes parameters that describe heterogeneity not accounted for by the predictors. In contrast to most other approaches, a nonparametric specification of the latent mixing distribution is used, leading to a formulation based on scaled latent classes. We examine the relationship between this model and several other models, give a tractable formulation of the likelihood function and likelihood equations, present an algorithm for maximum-likelihood estimation, and analyze marginal and conditional latent structures. The approach is illustrated with longitudinal data from the German Socioeconomic Panel.
