## Stata weights

fweights, iweights, and pweights may be speciﬁed using stset; see[ST] stset. Weights are not supported with efron and exactp.

_{Multilevel models with survey data . Stata's xtmixed command for fitting linear multilevel models now supports survey data. Sampling weights and robust/cluster standard errors are available. Sampling weights are handled differently by xtmixed than by other commands: . Weights can (and should be) specified at every model level unless you wish to assume equiprobability sampling at that level.In addition to weight types abse and loge2 there is squared residuals (e2) and squared fitted values (xb2). Finding the optimal WLS solution to use involves detailed knowledge of your data and trying different combinations of variables and types of weighting. weight, statoptions ovar is a binary, count, continuous, fractional, or nonnegative outcome of interest. tvar must contain integer values representing the treatment levels. tmvarlist speciﬁes the variables that predict treatment assignment in the treatment model.
