Examples: Multilevel Mixture Modelingu1 u2 u3 u4iscWithinc#1BetweenIn this example, the two-level latent class growth analysis (LCGA)shown in the picture above is estimated. This example is the same asExample 8.10 except that it has been extended to the multilevelframework. A growth model is not specified in the between part of themodel because the variances of the growth factors i and s are zero inLCGA. The filled circle on the circle containing the categorical latentvariable c represents the random mean of c. In the between part of themodel, the random mean is shown in a circle because it is a continuouslatent variable that varies across clusters.The CATEGORICAL option is used to specify which dependentvariables are treated as binary or ordered categorical (ordinal) variablesin the model and its estimation. In the example above, the latent classindicators u1, u2, u3, u4, u5, and u6 are binary or ordered categoricalvariables. The program determines the number of categories for eachindicator. In this example, u1, u2, u3, and u4 are three-categoryvariables.329
