Many researchers estimate the heterogeneity of treatment effects using linear regression, but newer methods rely on machine learning, for example Green and Kern (2012), Imai and Ratkovic (2013), Taddy et al. (2016), and Athey and Imbens (2016a).
Abacwaningi abaningi bacatshangisa ukuthi ukuphathwa kwemithi yokwelashwa okungafani nokusebenzisa ukuguqulwa komzimba, kodwa izindlela ezintsha zithembele ekufundeni komshini; bheka, isibonelo, Green and Kern (2012), u- Imai and Ratkovic (2013), Taddy et al. (2016), no- Athey and Imbens (2016a).
