speff2trial (1.0.0)
Semiparametric efficient estimation for a two-sample treatment effect.
http://cran.r-project.org/web/packages/speff2trial
The package performs estimation and testing of the treatment effect in a 2-group randomized clinical trial with a quantitative or dichotomous endpoint. The method is a special case of Robins, Rotnitzky, and Zhao (1994, JASA). It improves efficiency by leveraging baseline predictors of the endpoint. The method uses inverse probability weighting to provide unbiased estimation when the endpoint is missing at random.
