Findings that have different beliefs commonly considered to assess the ATT. Next, we tell you balance regarding the covariates and you will prominent support examination when you look at the purchase getting clear about the estimate. Third, OLS estimators in addition to suffer from new curse away from multidimensionality. Finally, the PSM estimator does not enforce as numerous constraints with the useful mode due to the fact OLS.
sixteen. The process to own estimating this formula is similar to Equation (2), yet not in place of bringing variations in the brand new blog post-therapy period, we and just take differences in the fresh new pre-cures several months.
