  <dc:title>Early Testing for a Treatment Effect using Surrogate Marker
Information</dc:title>
  <dc:title>R package SurrogateTest version 1.3</dc:title>
  <dc: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, 75(4):1253-1263. &lt;doi:10.1111/biom.13067&gt;.</dc:description>
