powerSurvEpi: Power and sample size calculation for survival analysis of
This package includes a set of functions to calculate
power and sample size for testing main effect or interaction
effect in the survival analysis of epidemiological studies
(non-randomized studies), taking into account the correlation
between the covariate of the interest and other covariates.
Some calculations also take into account the competing risks
and stratified analysis. This package also includes a set of
functions to calculate power and sample size for testing main
effect in the survival analysis of randomized clinical trials.
