The QUANTSELECT Procedure (Experimental)
WEIGHT Statement
WEIGHT variable ;
A WEIGHT statement names a variable in the input data set with values that are relative weights for a weighted quantile regression fit.
Values of the weight variable must be nonnegative. If an observation’s weight is 0, the observation is deleted from the analysis. If a weight is negative or missing, it is set to 0, and the observation is excluded from the analysis.
