Frequently I use kwallis, ranksum, or nptrend for testing between
groups, depending on the nature of the variables involved.  Stata
doen't support these tests in survey-weighted data.

Are there any equivalent tests to use when comparing weighted data?
Survey-weighted data can use Pearson's chi-square or Wald, but my
understanding is that neither is equivalent.

As background, the weights are inverse probability weights derived
from a propensity score model.  I have a cluster variable, but as far
as I know that doesn't matter with non-parametric tests anyhow.

Thanks for any thoughts,

Janet
