The multiple uses of the GROUP and the MODEL statements characterize the multiple-group multiple-model analysis. Unlike the single-group analysis, the order of some statements in a multiple-group multiple-model syntax is important for parsing purposes.
A GROUP statement signifies the beginning of a group specification block and designates a group number for the group. The scope of a GROUP statement extends to the subsequent subsidiary group specification statements until another MODEL or GROUP statement is encountered. In the preceding syntax, GROUP 1 and GROUP 2 have separate blocks of subsidiary group specification statements. By using additional GROUP statements, you can add as many groups as your situation calls for. Subsidiary group specification statements declared before the first GROUP statement are in the scope of the PROC CALIS statement. This means that these subsidiary group specification statements are applied globally to all groups unless they are respecified locally within the scopes of individual GROUP statements.
A MODEL statement signifies the beginning of a model specification block and designates a model number for the model. The scope of a MODEL statement extends to the subsequent main and subsidiary model specification statements until another MODEL or GROUP statement is encountered. In the preceding syntax, MODEL 1 and MODEL 2 have separate blocks of main and subsidiary model specification statements. By using additional MODEL statements, you can add as many models as your situation calls for. If you use at least one MODEL statement, any main and subsidiary model specification statements declared before the first MODEL statement are ignored.
Some model analysis statements are also bounded by the scope of the MODEL statements. These statements are: DETERM, EFFPART, LMTESTS, and STRUCTEQ. These statements are applied only locally to the model in which they belong. To apply these statements globally to all models, put these statements before the first MODEL statement.
Other model analysis statements are not bounded by the scope of the MODEL statements. These statements are: FITINDEX, SIMTESTS, and TESTFUNC. Because these statements are not model-specific, you can put these statements anywhere in a PROC CALIS run.
Optimization and other statements are not bounded by the scope of either the GROUP or MODEL statements. You can specify them anywhere between the PROC CALIS and the run statements without affecting the parsing of the models and the groups. For clarity of presentation, they are shown as last statement block in the syntax. Notice that the BY statement is not supported in a multiple-group setting.
