The following statements are available in the PSMATCH procedure:
[color=var(--color-text-primary)]PROC PSMATCH
[color=var(--color-text-primary)]ASSESS
[color=var(--color-text-primary)]BY
[color=var(--color-text-primary)]CLASS variables;
[color=var(--color-text-primary)]FREQ variable;
[color=var(--color-text-primary)]ID variable;
[color=var(--color-text-primary)]MATCH <options>;
[color=var(--color-text-primary)]OUTPUT OUT <(OBS=obs-value)>=SAS-data-set <keyword=name <keyword=name …>> ;
[color=var(--color-text-primary)]PSDATA TREATVAR=treatvar <(trt-option)> ps-option;
[color=var(--color-text-primary)]PSMODEL treatvar <(trt-option)> = <effects> </ WEIGHT=weight> ;
[color=var(--color-text-primary)]PSWEIGHT <options>;
[color=var(--color-text-primary)]STRATA <options>;
The PROC PSMATCH statement invokes the PSMATCH procedure. The CLASS statement and either a PSMODEL or PSDATA statement are required. If a PSMODEL statement is specified, the CLASS statement must precede the PSMODEL statement.
The MATCH, PSWEIGHT, and STRATA statements perform matching, weighting, and stratification, respectively. Only one of these statements can be specified.
