I am trying to use R. My question is if R can calculate a random effect
probit model {e.g. glmm} but including sampling weights. I am desperately
looking for a random effect model but wanted to use it on survey data.
Thanks for an answer: Niko Speybroeck.
Hi Niko,
look at functions `GLMM' (package: lme4) and `glmmPQL' (package:
MASS).

Hello,
I have been looking around in past helps about cross-correlations for a set
of n time series.
Although you can do it by yourself calculating the out-of-the-diagonal terms
in the cross correlation matrix by using pairwise combinations of ccf and
the diagonal terms by using acf, this does
Hi Dimitris,
Thanks a lot for the answer! I see that in glmm you can specify weight= but
this is according to me corresponding to for example the frequency of a
certain observation and not to an weighing factor because of the sampling
design. Tell me if I'm wrong. Do you have an example with GLMM

I want to create a general AR(p) correlation matrix and I'm using the

Any ideas how I can fix this?

I believe in the earlier discussion it was Spencer Graves that pointed out
that there is earlier work by DuMouchel using design information but not
weights as predictors.
The reference for the use of design weights as predictors is:
