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.
