Hi. Has any body come up with an answer to this question below on how to use
survey (analytical) weights with bootstrap quantile regression in STATA? (I have
an application similar to the one below)
Couldn't one run bsqreg with weighted data, ie., on the transformed model:
y*w = a w + b x*w
where w= obs. i weight/total population size, presuming that the resampling of
reweighted data builds in the required adjustment to the contribution of each
observation to the estimate of the sampling variability of b at each quantile.
But the problem is that STATA quantile regression commands don't allow to
specify the option of no intercept!
Any help will be appreciated.

I would like to run a quantile regression with bootstrapped standard
errors with a household survey dataset that has weights. However, the
BSQREG command does not allow weights.
The weights are integers (say, between 40 and 2600) such that adding
them up gives the total population of each city (though I'm working with
one city only right now - no PSUs or clusters).
The only reference I could fin on Statalist was the email from W. Gould
copied below - however, I can't figure out the correct way to implement
his suggestions in the quantile regression case. I emailed Stata support
and they only replied that implementing weights in BSQREG was not in
their plans, and that the email below could be useful...
Has anyone encountered similar problems? I went into the BSQREG code but
it was too obscure for me. Any help will be greatly appreciated!
Thank you very much
