To phrase it differently, i examine people who have similar inclination score and take the real difference within the results for the individuals
fourteen. This is basically the procedure i go after so you’re able to imagine the results: step one. Imagine new tendency get, 2. Suits somebody according to research by the propensity score.
15. Getting evaluation aim i additionally include the outcomes regarding a straightforward normal the very least squares (OLS) regression. not, i focus on one PSM is preferred more than regression for several reasons. Very first, PSM only takes into account findings that have comparable philosophy in the newest inclination get. Observations having dissimilar bunu okumaya devam edin beliefs commonly taken into account in order to estimate the fresh ATT. 2nd, i tell you balance regarding the covariates and you may popular help tests in the acquisition to get transparent regarding estimate. 3rd, OLS estimators also suffer with the newest curse of multidimensionality. And finally, the brand new PSM estimator does not impose as many constraints toward functional function as the OLS.
16. The process to have estimating so it equation is similar to Formula (2), yet not instead of taking differences in the brand new post-treatment months, i and just take variations in new pre-medication several months. Eg, toward effect on education we do the huge difference adopting the adolescent maternity enjoy ranging from therapy and you may handle with no huge difference just before the fresh new teenage maternity event.
