Dear SteveDenham, I run the data according to example # 40.5. In any run I found the value of zero was estimated for gp=1. The error in Log file and some part of the results are below: 1095 ; 1096 proc genmod; 1097 class gp time dog; 1098 model comfort=gp|time / dist=multinomial type1; 1099 repeated subject=dog (GP)/ corr=ind corrw; 1100 run; WARNING: TYPE1 tests are not available with the REPEATED statement. NOTE: PROC GENMOD is modeling the probabilities of levels of comfort having LOWER Ordered Values in the response profile table. One way to change this to model the probabilities of HIGHER Ordered Values is to specify the DESCENDING option in the PROC statement. NOTE: Algorithm converged. NOTE: The scale parameter was held fixed. NOTE: The working correlation table is not created for this model. WARNING: The generalized Hessian matrix is not positive definite. Iteration will be terminated. ERROR: Error in parameter estimate covariance computation. ERROR: Error in estimation routine. NOTE: The SAS System stopped processing this step because of errors.
