The SURVEYMEANS Procedure

Syntax

The following statements are available in PROC SURVEYMEANS.

PROC SURVEYMEANS < options > < statistic-keywords > ;: BY variables ;; CLASS variables ;; CLUSTER variables ;; STRATA variables < / option > ;; VAR variables ;; WEIGHT variable ;

The PROC SURVEYMEANS statement invokes the procedure. It optionally names the input data sets and specifies statistics for the procedure to compute. The PROC SURVEYMEANS statement is required.

The VAR statement identifies the variables to be analyzed. The CLASS statement identifies those numeric variables that are to be analyzed as categorical variables. The STRATA statement lists the variables that form the strata in a stratified sample design. The CLUSTER statement specifies cluster identification variables in a clustered sample design. The WEIGHT statement names the sampling weight variable. You can use a BY statement with PROC SURVEYMEANS to obtain separate analyses for groups defined by the BY variables.

All statements can appear multiple times except the PROC SURVEYMEANS statement and the WEIGHT statement, which can appear only once.

The rest of this section gives detailed syntax information for the BY, CLASS, CLUSTER, STRATA, VAR, and WEIGHT statements in alphabetical order after the description of the PROC SURVEYMEANS statement.
