st: Re: Generating first-differences in regression coefficients

["Michael Blasnik" <michael.blasnik@verizon.net>]

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.
