Scale mixtures of uniform distributions are used to model non-normal data in both univariate and multivariate settings. In addition to providing greater modelling flexibility, the use of scale mixtures of uniforms also results in straightforward computational strategies, particularly in a...

We propose a maximum likelihood framework for estimating finite mixtures of multivariate regression and simultaneous equation models with multiple endogenous variables. The proposed “semi‐parametric” approach posits that the sample of endogenous observations arises from a finite mixture of...

Various research areas face the methodological problems presented by nonnegative integer count data drawn from heterogeneous populations. We present a disaggregate negative binomial regression procedure for analysis of count data observed for a heterogeneous sample of cross-sections, possibly...
