The log-linear models can be thought of to be on a continuum with the two extremes being the simplest model and the saturated model.
Typically this test is performed after the algorithm has converged on a solution.

Another more-or-less distinctly medical LCA application is evaluation of diagnostic tests in the absence of a "gold standard." For example, if one has several tests for detecting presence/absence of a disease, but no comparison "gold standard" that indicates disease status with certainty, LCA can.
