The goal of survParamSim is to perform survival simulation with parametric survival model generated from ‘survreg’ function in ‘survival’ package. In each simulation, coefficients are resampled from variance-covariance matrix of parameter estimates, in order to capture uncertainty in model parameters.


You can install the package from CRAN.



This GitHub pages contains function references and vignette. The example below is a sneak peek of example outputs.

First, run survreg to fit parametric survival model:

Next, run parametric bootstrap simulation:

Calculate survival curves with prediction intervals:

Calculate hazard ratios with prediction intervals:
