Problem Note 33093: Floating Point Zero Divide may occur in PROC HPMIXED with WEIGHT statement
If you have small values close to zero for your WEIGHT variable, then PROC HPMIXED may report a floating point overflow or other error in the SAS log.
To avoid the problem, use PROC MIXED to fit the model.
