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] Ariel Date: Mon, 1 Oct 2012 15:39:59 +0100 (BST) From: Paula Arce <paulaarce@rocketmail.com> Subject: Re: st: Matching samples in Stata 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?
