speff2trial (version 1.0.0)
Semiparametric efficient estimation for a two-sample treatment
effect
Description
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.
