select glmm r function
Hello , I have to make a choice to compute a delta-Glmm and i would like to have your comments. I must to make a delta-glmm (binomial/gamma) with an ARMA correlation. I think that i must choose the glmmPQL function but i have few questions. (1)PQL is realy good for the binomial model (Breslow,2003)? (2)Can i compute a CorStruct whit an other R function ( glmer? visibly not (Package comparisonin wikidot) )? (3)If i use GlmmPQL ,how to select the significants variables and their orders whitout AIC or BIC? Thank you for your time .Xavier.C
