Abstract: Latent class methodology has been used extensively in market research. In this approach, segment membership and parameter estimates for each derived segment are estimated simultaneously. A popular approach for fitting latent class models to rating responses is to assume mixtures of multivariate conditional normal distributions. An alternative approach is to assume a Proportional Odds model. These two approaches are compared empirically in a Monte Carlo study, assessing segment membership and parameter recovery, goodness of fit and predictive accuracy.
