In this section, I suggested that pre-treatment information can be used to improve the precision of estimated treatment effects, but there is some debate about this approach; see Freedman (2008), W. Lin (2013), Berk et al. (2013), and Bloniarz et al. (2016) for more information.
Am Kapitel, recommendéiert ech dass Précoce-Behandlung Informatiounen benotzt ka der Präzisioun vun geschate Behandlung Effekter ze verbesseren, mä et ass eng Debatt iwwert dës Approche: Freedman (2008) , Lin (2013) , an Berk et al. (2013) ; gesinn Bloniarz et al. (2016) fir méi Informatiounen.
