CHAPTER 17These are used to specify parameters that are specific to thecombinations of classes for those two categorical latent variables.Categorical latent variables can be combined in sets involving all but onecategorical latent variable. For example, with three categorical latentvariables c1, c2, and c3, combinations of up to two categorical latentvariables are allowed. Following is an example of how this is specified:MODEL c1.c2:%c1#1.c2#1%where %c1#1.c2#1% refers to a combination of class 1 for c1 and class 1for c2.MODEL:%OVERALL%%class label%The MODEL command used in conjunction with %OVERALL% and%class label% is used to describe the overall and class-specific modelsfor mixture models. Statements following %OVERALL% refer to themodel common to all latent classes. Statements following %classlabel% refer to class-specific model statements.Class labels are created by adding to the name of the categorical latentvariable a number sign (#) followed by the class number. For example,if c is a categorical latent variable with two latent classes, the classlabels are c#1 and c#2.MODEL:%WITHIN%%BETWEEN%The MODEL command used in conjunction with %WITHIN% and%BETWEEN% is used to describe the individual-level and cluster-levelmodels for multilevel modeling. The statements following %WITHIN%describe the individual-level model and the statements following%BETWEEN% describe the cluster-level model. With multilevelmixture models, the %OVERALL% and %class label% specifications624
