这个control 和 compare group 已经选定,怎么使用这个propsensity score matching process 在SAS里应用呢?

The following statements are available in the PSMATCH procedure:
<options>;[color=var(--color-text-primary)]ASSESS
<ALLCOV> <LPS> <PS> <VAR=(var-list)> </ assess-options> ;[color=var(--color-text-primary)]BY
variables;
[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.
