Problem Note 39491: WEIGHT statement does not work correctly with ERRORMODEL statement when general likelihood is specified
If you specify a WEIGHT statement and specify a general likelihood function on the ERRORMODEL statement, then the WEIGHT statement is not appropriately weighting the likelihood function by the WEIGHT variable.
To circumvent the problem, you will need to incorporate the weight directly into the likelihood function when specifying the ERRORMODEL statement to avoid using the WEIGHT statement.
