Dear all,

I have fitted a Rasch model to some data with glmer. From the results of 
this analysis (namely the item difficulty estimates) I would like to 
compute the posterior probability of any ability/attitude value, given 
some pattern of observed responses.

What I would need are the quadrature points and weights that are used in 
a glmer analysis, assuming that the latent ability values are drawn from 
a gaussian. I can't find them in the result object slots (or did I miss 

Thank you in advance for any hint,
