The latent class approach can be exploited for a number of distinctive modeling uses.

This paper presents a flexible logit regression approach which allows to regress the latent states occupied at the various points in time on both time-constant and time-varying covariates. The regression approach combines features of causal log-linear models and latent class models with explanatory variables. • models for observed response variables of other scale types, such as variables which are ordinal, continuous, or counts (Dias, Ramos & Vermunt, 2007); • models for multilevel data similar to the multilevel latent class models pro-posed by Vermunt (2003). Not only more extended models can be dealt with, but it is also possible to perform Latent GOLD® 4.0 User’s Guide. Latent classes are unobservable (latent) subgroups or segments. Cases within the same latent class are homogeneous on certain criteria, while cases in different latent classes are dissimilar from each other in certain important ways. In statistics, the logistic model (or logit model) is used to model the probability of a certain class or event existing such as pass/fail, win/lose, alive/dead or healthy/sick.This can be extended to model several classes of events such as determining whether an image contains a cat, dog, lion, etc. Each object being detected in the image would be assigned a probability between 0 and 1, with ...This latent class multinomial-logit (LC-MNL) demand model scales the complexityof the assortment problem from polynomial when segments are disjoint (e.g., see [13] or [21]) to NP-Hard (as proved inour former paper [18]), but brings enough flexibility into the model so that more realistic preferences can be captured.For example, in retailing ...
