I'm not sure about the full question, but you should at least look at -whelp pctile- to see that pctile does not have a percentiles option. The help file shows that option exists for the _pctile command, which will return results in r(), perhaps allowing you to proceed the the bootstrap approach.

for any coefficient. I tried using -pctile- with this, but it wouldn't let
me use the -percentiles()- option:

. pctile pct = b_turn0105, nq(4) p(15.87 50 84.13) genp(pc)
option p() not allowed
r(198);

. pctile pct = b_turn0105, nq(4) percentiles(15.87 50 84.13) genp(pc)
option percentiles() not allowed
r(198);

. pctile pct = b_turn0105, percentiles(15.87 50 84.13) genp(pc)
option percentiles() not allowed
r(198);

. pctile pct = b_turn0105, percentiles(15.87 50 84.13)
option percentiles() not allowed
r(198);

If anyone knows of any canned post-estimation solutions for generating FDs
in regression coefficients, then I'd be very grateful to you.
