## Survival extrapolation using Stata

Learn how to extrapolate survival data in Stata

## Estimate relative survival $:$ tied data vs. untied data

rs.surv in R and stpp, strs, stnet in Stata are applied to estimate relative survival. What should we pay attention to as using tied/untied data? Why are the estimates different?

## Make ratetable using R

An alternative approach to constructing a ratetable object in R by fitting a multiple time-scale flexible parametric models using individual-level data
