Problem Note 50729: Missing or incorrect exact confidence limit for Poisson model
When the MODEL statement option DIST=POISSON and the EXACT statement are specified in PROC GENMOD, in some cases (which cannot be determined in advance), the search for exact confidence limits for a parameter in the Poisson model might fail. As a result, the limit might be shown as missing or might be incorrect. There is no circumvention for this problem.
