Unfortunately, xtmixed does not support these kind of weights. This model is called "V-known" and the only way I have found to estimate it is to use the software package HLM. I have heard that this model is equivalent to putting SE(Y) in the model as a covariate, but I haven't been able to convince myself of that.

I would like to estimate a model of the following form:

where Y_ij is the municipal poverty rate (from a household survey)
X_ij are municipal characteristics (from a population Census)
u_i are the region level random effects (municipalities are nested
within regions).

With xtmixed, this would look like: xtmixed mun_pov X_ij || region:
Since municipal poverty rates are sample estimates, they have
corresponding sampling variances. How would one properly incorporate
this uncertainty into the xtmixed setup?

Any advice would be much appreciated.
