%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.
