The -outvar- in -psmatch2 is the outcome variable. In other words, if you
want to see if medical students have a significantly (statistically)
different outcome than non-medical students, you could plug that variable in
to -out()-, however the matching code will run perfectly fine without
specifying the outcome. That only means that you'll need to analyze the
outcome on your own after matching, ie:
regress outcome treatment [_weight]

Thank you - I downloaded the command -
Even after looking at the help command I am slightly unsure what I need to
specify where.
Should I first type the variable that codes the student type (1 for medical
0 for the rest) followed by the SES variables I want to match them on?
psmatch2 student_type SES1 SES2, out(outvar)
Is the out(outvar) command going to produce a variable which lets me know
what participants from the 'other student' group are used as match for the
medics? if not how can I obtain this?
Thanks,
Paula

The command -psmatch2- [not a macro in Stata terms] must be downloaded
from SSC before you can read its help.
