powerSurvEpi (version 0.1.5)
Power and Sample Size Calculation for Survival Analysis of
Epidemiological Studies
Description
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 and conditional logistic regression for nested case-control study.
