title: 'survSampleSize: Sample Size Calculator for Survival Endpoint Clinical Trials'
version: 0.1.2
doi: 10.32614/CRAN.package.survSampleSize
abstract: An interactive 'shiny' application for sample size and power calculation
  under general conditions for clinical trials with survival endpoints. Implements
  the weighted log-rank method of Lu (2021) <https://doi.org/10.1002/pst.2069> via
  the 'lrstat' package, supporting non-proportional hazards, delayed treatment effects,
  unequal allocation and dropout, as well as the classic method of Freedman (1982)
  <https://doi.org/10.1002/sim.4780010204> via the 'powerSurvEpi' package. Results
  are presented interactively with survival curves and event-prediction timelines.
