Convergence and singularity in glmmPQL
Greetings-
Using R 1.5.0 under linux and the latest MASS and nlme, I am trying to
develop a three-level (two levels of nesting) model with a dichotomous
oucome variable. The unconditional model is thus:
> doubt1.pql<-glmmPQL(fixed = r.info.doubt ~ 1, random = ~1 |
groupid/participantid,
+ family = binomial, data = fgdata.10statements.df)
iteration 1
iteration 2
iteration 3
iteration 4
iteration 5
> summary(doubt1.pql)

Simulation confidence interval
...[l]*cibeta>0)????????????? powaprox[[l]]<-powaprox[[l]]+1
????? sdepower[l,iter]<-as.numeric(sdebeta[l])
? }
?
Estbeta recovers the fixed effects from a model fitted using lmer.
Beta is defined elsewhere and is a user specified input
that relates the?data generated in the simulation to an oucome.?
So, it seems pretty clear that the third line from the bottom is
a clever test of whether the confidence interval traps 0.? My
question is why use beta[l]*cibeta>0 rather than
estbeta[l]*cibeta>0.? Is that because in the long run the model
parameter etimates tend toward the betas speci...
