singular convergence in glmmPQL

dave fournier


If you are having trouble with convergence in glmmPQL
you might want to try our glmmADMB package for R at

It is more stable according to some users.

I believe the corresponding commands for
your model are

# paste this after your other commands
# load glmmADMB package
# invoke glmmADMB routine
 re.1 <- glmm.admb(y.long ~ arm.long,

and that should do it.
