Problem Note 7104: Incorrect results with FREQ and/or WEIGHT statement when DIST=NEGBIN
If you use a WEIGHT and/or FREQ statement in conjunction with the
DIST=NEGBIN option in the MODEL statement, all results will be
incorrect.
To circumvent the problem, if you are using a FREQ statement, generate
repeated observations rather than using the FREQ statement. There is no
circumvention if you are using a WEIGHT statement.

issue is available at:
