Problem Note 71126: The STDIZE procedure might produce incorrect weighted results when you specify the MISSING=value option
 |  |  |  |  |
PROC STDIZE might compute incorrect results when the following conditions are met:
- You specify the MISSING=value option in the PROC STDIZE statement.
- There are no missing values for the analysis variable.
- You specify a WEIGHT statement.
- One or more of the WEIGHT variable values are zero (0).
Depending on the order of observations in the input data set, PROC STDIZE can compute an incorrect value for the sum of weights used in the analysis. When this issue occurs, the scale and standardized values are also computed incorrectly.

If you specify the MISSING=value option and a WEIGHT statement and the weight variable contains one or more observations with a value of zero, PROC STDIZE might produce incorrect results.
