A Latent Class Analysis to Support New Diagnose Criteria for Gambling Disorder in DSM5 - A Bayesian Approach

Classification/Segmentation

Some describe segmentation as simply classifying an entire population based on a few levels of a single factor; I would see it more from a machine learning perspective - it can be as simple as using a logistic regression to differentiate a population based on covariates, or as complex as clustering models based on distance matrices or latent measurement models. The statistical segmentation techniques include support vector machines (SVMs), K-means, classification trees, latent class analysis and more.

The plot resulted from a LCA shows that the "Illegal Acts" criterion has a low probability of being met among patients with gambling disorder, which in another way supports the validity of eliminating this criterion in the new DSM5.  The ultimate result for LCA is to give the probability for a person to be classified in a certain class, based on Bayes rules.
