| Subject | Re: st: How to use weights in a random effect model |

-gllamm- ("findit") does random effects models and takes: 1) probability weights and 2) sampling clusters (i.e. primary sampling units or PSUs) that are not part of the model. A Google search for "gllamm pweight"and "multilevel sampling weights" will turn up related posts. You will find advice to rescale the probability weights if you are interested in estimating the variance components. HLM, if you have access to it, would be a good alternative to GLLAMM.

In addition, I would like to use weights in the model. I Know that I can use iweights with xtreg, mle. But then I can get the message "iweights must be constant within model". Is there any way I can use aweights oder pweights in my random effect model?
Thanks a lot.
