Implements the weighted log-rank method of Lu (2021) <doi: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) <doi:10.1002/sim.4780010204> via the 'powerSurvEpi' package. Results are presented interactively with survival curves and event-prediction timelines.https://github.com/r-universe/jianghuai0730/actions/runs/27908501704Sun, 21 Jun 2026 10:40:02 GMTsurvSampleSize0.1.2successhttps://jianghuai0730.r-universe.devhttps://github.com/cran/survSampleSizesurvSampleSize.RmdsurvSampleSize.htmlGetting started with survSampleSize2026-06-20 14:00:022026-06-20 14:00:02
