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 the procedure omits that observation from the analysis. See the section Missing Values for more information. The WEIGHT statement allows one weight variable.
If you do not specify a WEIGHT statement but provide replicate weights with a REPWEIGHTS statement, PROC SURVEYPHREG uses the average of each observation’s replicate weights as the observation’s weight.
If you specify neither a WEIGHT statement nor a REPWEIGHTS statement, PROC SURVEYPHREG assigns all observations a weight of one.
