fifteen. To possess testing objectives i include the results from an easy typical least squares (OLS) regression. not, i emphasize that PSM is recommended more than regression for a couple grounds. Earliest, PSM merely takes into account findings with quite similar beliefs during the new propensity score. Observations having unlike thinking are not taken into account to help you estimate the fresh ATT. Second, i reveal balance in the covariates and you may well-known help testing inside the purchase become clear about the estimate. 3rd, OLS estimators plus have problems with brand new curse from multidimensionality. Last but not least, the brand new PSM estimator doesn’t enforce as numerous constraints on the useful means given that OLS.
16.
