Active 1 year, 5 months ago. The basic syntax of the teffects command when used for propensity score matching is: teffects psmatch (outcome) (treatment covariates) In this case the basic command would be: teffects psmatch (y) (t x1 x2) However, the default behavior of teffects is not the same as psmatch2 so we'll need to use some options to get the same results. A quick example of using psmatch2 to implement propensity score matching in Stata. htm recommends now of propensity score matching in python is.

At first glance, both the propensity score matching DID (PSM DID) and the inverse probability weighting (IPW DID) that you want to do are sensible ways to approach this: matching and weighting will take care of the selection into treatment based on observables, and the DID will deal with selection on unobservables as long as the bias from it is time-invariant, conditional on covariates. search instead of re. edu The propensity score for a subject is the probability that the subject was treated, P(T=1).
