[R] why does lmer not give p valuses for quasibinomial family?

[Szentirmai Istvan]

Dear All,

I'm running a binomial model using the lmer() function, and I get p values 
for the parameter estimates only with family=binomial, but not with 
quasibinomial? Why is that so? I wanted to use quasibinomial family, because 
my data were overdispersed.

Thanks,
Istvan
