One possibility might be the -rcentile- package, which users can download from SSC, and which computes confidence intervals for medians (and other percentiles) allowing for clustering and/or sampling-probability weights.

The -rcentile- package requires the -somersd-, -scsomersd- and -expgen- packages in order to work. If you are using Stata Version 10, then you should download the Stata Version 10 versions of these packages from my website by typing, in Stata,

net from "http://www.imperial.ac.uk/nhli/r.newson/stata10/";

and downloading the Stata Version 10 versions of all these packages.

I hope this helps.

Best wishes

Roger

Dear All,

I working on  MeasureDHS surveys (2-stage cluster sample) and I'm trying to
estimate weighted median using Stata10.
I've tried several ways, but none seems to work:
iweight or pweight are not allowed with 'sum var,d' or 'centile var' or
'qreg var'.
When I use quantile regression for the median to get standard errors, qreg
is not supported by svy.

What could I do?
Thanks for your answers
