We naturally have hypotheses … WebLATENT CLASS ANALYSIS Latent class analysis is a statistical method used to identify unobserved or latent classes of individuals from observed responses to categorical variables (Goodman, 1974). It is analogous to factor analysis which is commonly used to identify latent classes for a set of continuous variables (Gorsuch, R. L.,1974).

Then it has Stata re-fit the model, with one parameter constrained. Here's some previous discussion of the issue.

WebIn multiple-group LCA models, individuals are dependent owing to multilevel data structure, where observation units (i.e., individuals) are nested within a higher-level unit (i.e., group).
