The latest version of the -psmatch2- package contains an updated and revamped -pstest-.
It now has three main types of uses (outlined below), can graph (dot chart or histogram) balancing measures, displays the output in a more compact and useful way (including the option of displaying only those variables which are significantly unbalanced, ie p<=0.10).
Please note however that the syntax of -pstest- has slightly changed (in a hopefully more intuitive and nimble way).
You can use -pstest- to assess comparability in terms of a set of covariates between:
1. two matched samples after psmatch2 (the default), as in:
    . psmatch2 treatedvar Xvarlist [, ...]
    . pstest
2. any two samples, eg the raw samples before performing matching or completely unrelated to matching purposes (in the latter case the -if- condition can be useful)
3. two samples before and after having performed matching. This was what the old pstest would do.
To get it type within Stata:
. ssc install psmatch2, replace
or
. adoupdate psmatch2, update.
Please do check the helpfile for -pstest- for the full details.
