Findings which have dissimilar viewpoints commonly taken into account so you’re able to estimate new ATT. Next, i show balance throughout the covariates and you can popular help tests inside the buy becoming clear towards estimation. 3rd, OLS estimators in addition to suffer from the fresh curse off multidimensionality. Finally, brand new PSM estimator does not demand as numerous limits for the functional mode as OLS.
sixteen. The process to have estimating so it formula is like Formula (2), not in the place of taking differences in new post-cures months, i in addition to Yemen kadД±n sД±cak need variations in the fresh new pre-procedures several months.
