Title: Early Testing for a Treatment Effect using Surrogate Marker
Information
Version: 1.2
Date: 2020-03-26
Version: 1.3
Date: 2021-11-15
Author: Layla Parast
Maintainer: Layla Parast <parast@rand.org>
Description: Provides functions to test for a treatment effect in terms of the difference in survival between a treatment group and a control group using surrogate marker information obtained at some early time point in a time-to-event outcome setting. Nonparametric kernel estimation is used to estimate the test statistic and perturbation resampling is used for variance estimation. More details will be available in the future in: Parast L, Cai T, Tian L (2019). Using a Surrogate Marker for Early Testing of a Treatment Effect. Biometrics, In press.
