I need to estimate sensitivity, specificity, PPV and NPV for clustered data using GEE and programming in SAS. I will use PROC GENMOD with dist=binomial link=log. However it is not clear to me how the model should be specified. E.G. How should I tell sas to calculate for se the probability of true positives on true positives + false negatives?
Is anybody there who can help me?
Thanks A LOT in advance
