...ht be better suited for my data. So I got the yags package and tried a model like this: > gee1<-yags(alive~sex*weight, family=binomial,id=id,corstr='exchangeable', alphainit=0.) But then the summary only gives me this: > summary(gee1) Length Class Mode 0 yagsResult list How do I get R to give me the parameter estimates, std errors, t- and p-values etc.? And if someone is willing to answer questions about the glmmPQL function, please let me know and I'll send you the most urgent questions, but I don't want to bother everyone with it. Many tha...
