do we need the _KM_strata
variable after ps
/md
-matching?
I would generally think, that we should report the number of strata only for em
, and also just report a variable of the propensity score instead of the strata
_KM_strata
is only kept if user requests the kmkeepgen
. Otherwise we have _nopo_strata
for em
and _nopo_ps
for ps
. em
and nn/bandwidth/ridge info for ps
and md
(depending on option, default is kernel matching with bwidth
reported.Closing.
There was a mistake in the code to the effect that the
_nopo_strata
captured the number of unique values of the propensity score (which we knew). After correction (which is pushed), the no. of strata forps
will always be1
(the same is true formd
, where strata anyhow make no sense in the distance metric).What should we do? Show strata only for
em
? We could also show the unique values for theps
, but then_nopo_strata
would be different from_KM_strata
.
