GLM, GLZ, GRM, PLS, GDA, and MANOVA Syntax - Keyword Groups

GROUPS [=] Variable [ (Value List) ] Variable [ (Value List) ] ... Variable [ (Value List) ];

Example. GROUPS = GENDER('MALE' 'FEMALE') GROUP(1 2) STATUS(*) TREATMENT;

Optional keyword; specify the categorical predictor variables, and, optionally, the code values (codes or text labels) that are used in the categorical predictor variables to denote the group membership of each observation. If no code values are specified, or if instead of code values an asterisk (*) is placed inside the parentheses following the respective factor, STATISTICA will use all values that are found in the datafile for the respective variables; note that, while reading the datafile to "find" all code values, STATISTICA will use casewise deletion of missing data.

Applies to. GLM, GLZ, GRM, PLS, GDA, ANOVA/MANOVA, GC&RT, and GCHAID.
