[R-sig-ME] select glmm r function

[xavier chevillot]

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
