Dear all,

I have a question on the use of weights in gllamm. I am estimating the standard Hopit model with anchoring vignettes (as in the example on the gllamm website, Each individual in the sample contributes with the self-evalutation and the evalutation of vignettes. Then, there are 2 levels: the first one consists of the single evalutations (self-evaluations OR vignette evaluations) and the second consists of ALL the evaluations provided by a given individual. I am not estimating any random effect. I use frequency weights.

Should I apply the same set of frequency weights to both levels by specifying two variables (say weight1 and weight2) that are equal? Or should I apply the weights to one level only? If the latter is true, which level should I consider?

Thanks in advance for any suggestion.
