st: "Alternate Solutions Exist" in Quantile Regressions (qreg)

[Jen Zhen <jenzhen99@gmail.com>]

Dear members of the Statalist,

when running
- qreg finw  ry5-ry13  d1995-d2003 d2005-d2007 ,  wlsiter(50) -
we get the note that "alternate solutions exist" in between iterations.

In an earlier list post
(http://www.stata.com/statalist/archive/2008-10/msg00519.html), it was
suggested to check whether the different alternate solutions differ
significantly, but Stata by default seems to give us only one. Do you
know a way to view the others, or other approaches to tackle this
issue?
Another suggestion made in that thread was to perturb the data and see
which of the answers remains, but we're not sure how to exactly
implement this perturbation. Should we just take all variables
currently used in the regression, add to them some small random error,
and then rerun the regression with those new variables? How large or
small should the error sensibly be?

Thanks,
J
