Abnormal termination and missing GEE score tests might result from using TYPE3 option and REPEATED statement in PROC GENMOD


In some cases, the use of the TYPE3 option in the MODEL statement in PROC GENMOD along with the REPEATED statement may result in abnormal termination of the procedure and errors such as floating point zero divide or floating point exception.

Additionally, the "Score Statistics For Type 3 GEE Analysis" table is not displayed. You might be able to circumvent this problem by including the WALD option in the MODEL statement in PROC GENMOD to request Wald tests rather that score tests.
