The following statements are available in PROC HPLMIXED.
PROC HPLMIXED <options>;
CLASS variables;
ID variables;
MODEL dependent = <fixed-effects> </ options>;
OUTPUT <OUT=SAS-data-set> <keyword <=name>>…<keyword <=name>> </ options>;
RANDOM random-effects </ options>;
REPEATED repeated-effect </ options>;
PARMS <(value-list) …> </ options>;
PERFORMANCE <options>;
Items within angle brackets ( < > ) are optional. The RANDOM statement can appear multiple times. Other statements can appear only once.
The PROC HPLMIXED and MODEL statements are required, and the MODEL statement must appear after the CLASS statement if a CLASS statement is included. The RANDOM statement must follow the MODEL statement.
Table 53.1 summarizes the basic functions and important options of the PROC HPLMIXED statements. The syntax of each statement in Table 53.1 is described in the following sections in alphabetical order after the description of the PROC HPLMIXED statement.
