Latent class analysis python

**Latent Class Analysis**(LCA) is a statistical method for finding subtypes of related cases (**latent classes**) from multivariate categorical data. For example, it can be used to find distinct diagnostic categories given presence/absence of several symptoms, types of attitude structures from survey responses, consumer segments from demographic and ...**Lccm**is a**Python**package for estimating**latent class**choice models using the Expectation Maximization (EM) algorithm to maximize the likelihood function. Main Features.**Latent Class**Choice Models. Supports datasets where the choice set differs across observations. Allows the analyst to capture correlation across multiple observations for the same respondent- So we will run a
