Hi--thank you for your reply. I read the SAS explanation on the reason for the error message in the log. My question is: how should I estimate the weight score per observation so I do not get the same error message? The current weight score is expressed in integers, which obviously does not work. The challenge I have is to figure out whether the weight score must be adjusted to the size of a specific stratum, all the strata that are used for sample specification, or something else that I am missing. Thank you.
