st: Testing survival-time medians with survey data

[<Arnold.Levinson@UCHSC.edu>]

Stata's survival time commands allow p-weights when estimating medians and when estimating confidence intervals of survival rates, but not confidence intervals of p-weighted medians. Is this because variance is undefined for that parameter, or can someone suggest how to compute it?
