speff2trial (version 1.0.1)
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, dichotomous, or right-censored time-to-event
endpoint. The method improves efficiency by leveraging baseline
predictors of the endpoint. The inverse probability weighting
technique of Robins, Rotnitzky, and Zhao (JASA, 1994) is used
to provide unbiased estimation when the endpoint is missing at
random.
