sensitivity, specificity, PPV and NPV for clustered data using GEE - PROC GLM

[fedith]

Dear All,

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

Why not use PROC LOGISTIC ?
And your link function is not right.

 dist=binomial link=LOGIT

Hi,

yes PROC LOGISTIC is an option as well.

LOGIT  Thanks 🙂
