We propose Multivariate Tobit models with a factor structure on the covaria
nce matrix. Such models are particularly useful in the exploratory analysis
of multivariate censored data and the identification of latent variables f
rom behavioral data. The factor structure provides a parsimonious represent
ation of the censored data and reduces the dimensionality of the integratio
n required in evaluating the likelihood. In addition, the factor model para
meters lend themselves to substantive interpretation and graphical display.
The models are estimated with simulated maximum likelihood.. Applications
to the prescription of pharmaceutical products and the analysis of multi-ca
tegory buying behavior are provided.
