The SURVEYIMPUTE Procedure

The WEIGHT statement names the variable that contains the sampling weights. This variable must be numeric, and the sampling weights must be positive numbers. If an observation has a weight that is nonpositive or missing, then PROC SURVEYIMPUTE omits that observation from the analysis. For more information, see the section Missing Values.

If you do not use a WEIGHT statement but you provide replicate weights in a REPWEIGHTS statement, PROC SURVEYIMPUTE uses the average of each observation’s replicate weights as the observation’s weight.

If you use neither a WEIGHT statement nor a REPWEIGHTS statement, PROC SURVEYIMPUTE assigns all observations a weight of 1.
