findit cdsimeq works fine; since this is part of a Stata Journal
article, and Stata knows about all contents in SJ / STB, just use
findit and click to install. This routine will not appear in SSC, since
there is no need to duplicate the SJ link. The exception to that rule
is when authors have updated their materials since they were published
in SJ / STB (and speaking as a member of the SJ editorial board,
authors are kindly requested to submit notice of such revisions to SJ,
which contains an Updates page).
