I would argue that your sample is too small to make general
statements about the use of Stata.
Unless Suzy comes from the same school where I teach now, I would add
my convenience sample to hers. Stata is pretty much unheard of in
mainstream statistics. We have a STAT 7xxx class on statistical
software that teaches SAS and S-plus/R, as all the medical folks are
using SAS, and all the top-notch statistical research is usually
implemented in R... or at least nobody will call Matlab or Fortran a
purely statistical software. So students see SAS as a must when
applying for industry jobs, and R is necessary to talk to our
professors because the latter use R themselves.
I personally think it is time for Stata Corp. to stop chickening out
of statstics market. Stata has all the programming tools statisticians
find in R (a matrix language, object-oriented tools, compiled code for
faster implementations, even interface with C which, to my memory, was
only used my James Hardin for the suite of measurement error GLMs).
And the more I work with SAS, the more I like Stata :))
