eg1. Lobo et al. 2006. Addressing the issue of channeling bias in observational studies with propensity scores analysis. Research in Social and Administratrative Pharmacy.
(在p.148。)
eg2. Reeve et al. 2008. Reducing Bias in Cancer Research: Application of Propensity Score Matching. Health Care Financial Review, vol.29, no.1.
(在p.72, p.73, 以及p.74Table 2的注释里面.)
p.s. 这两篇文章好像是都是先把propensity scores 分成quintiles, 然后再在各个quintile里检验balancing的。这个ms不是必须的吧?我是说,-pstest- 是对于整个sample一并检验的吧。
谢谢老师!
