st: RE: How do I obtain confidence intervals for percentiles with survey data ?

If you can't find anything else, you can bootstrap the percentiles 1000 times and get approximate confidence intervals.

Subject: st: How do I obtain confidence intervals for percentiles with survey data ?

Hello Everyone :

When I use the command centile Stata reports de centile requested as
well as the confidence interval.

Since I have survey data,  I have to use the command pctile but Stata
reports the percentile not the conffidence interval, ¿what can I do to
obtain the confidence interval?

This is the input commands I have been using :

-pctile pct = loghourlywage  [pw=weight], nq(100) genp(percent)

-list percent pct in 1/100

Thanks in advance for your help.
