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 balinganisela heterogeneity nemiphumela yokwelashwa usebenzisa ekuhlehleni komugqa, kodwa izindlela newer ancike umshini ofunda izinto, isibonelo Green and Kern (2012), Imai and Ratkovic (2013), Taddy et al. (2016), kanye Athey and Imbens (2016a).
