stpp calculates the Pohar-Perme non-parametric estimate of marginal relative survival, which under assumptions can be interpreted as marginal net survival. The estimate is a step function and changes at each event time.
This is a different implementation to
stns where the time-scale is split into a number of intervals.
stnet is another command
that can be used to give an estimate of marginal relative survival. The motivation for developing
stpp was to directly standardize
the estimates using both traditional standardization and by using individual weights.
The example currently just replicates the help file - I intend to add some additional text at a later stage.
