The LMIXED Procedure
CLASS Statement
The CLASS statement names the classification variables to be used as explanatory variables in the analysis. You can list the response variable for binary models in the CLASS statement, but this is not required. Table 10.3 summarizes the values that you can use as either an option or a global-option. The options are fully documented in the section CLASS Statement in Chapter 3: Shared Concepts.
Table 10.3: CLASS Statement Options
Option | Description |
|---|---|
Reverses the sort order | |
Treats missing values as valid levels | |
Specifies the sort order for the levels | |
Specifies the parameterization of the variable | |
Specifies the reference level of the variable and puts this level at the end of the list of levels. This interpretation of the specified REF= level does not apply when DMMETHOD=SPARSE because in this case the LMIXED procedure does not necessarily solve mixed model equations in the original order. |
