psmatch2 with STATA 18

[Tiziana Giuliani]

Hi everyone,

I am a beginner user of STATA (18th version); I have to run a matching/probit and I am using the command psmatch2 but after I launch the command, this message pops up.

psmatch2 w $xvars , out(y) neighbor(1) common

command psmatch2 is unrecognized

I have also tried the command help psmatch2 but no results are listed.

Can you pls help?

Thank you so much in advance...

I believe psmatch2 is a community contributed command and does not come bundled with Stata. You may need to install from ssc.

 ssc install psmatch2
