Hi Dale - and any other smart people out there ;o),
Thanks for your answer!
I actually tried that, using GENMOD... I have been working my way through Stokes (Categorical Data Analysis, pp533), but are having problems as my sample size are not adequate. In a two-way cross-classification of my explanatory variables the count for one cell is only two. And then the model crashes...
Is that different in PROC NLMIXED?
Besides, according to Harrell (Regression Modeling Strategies, chap 13, p. 335) the PO test is extremely anti-conservative. The p-value of the test was ~0.03 - and I wonder whether this could be acceptable anyway? PROC LOGISTIC does not allow me to take the clustering of my data into account - how does that affect the PO test?
Thanks,
Bodil
