STNET: Stata module to calculate net survival

stnet estimates net survival as proposed by Pohar Perme, Stare and EstEve (Biometrics 2011) by using a life tables approach. The command displays the results in life tables stratified by the variables specified in the by option. Optionally relative survival using the Ederer II method can be calculated. This command may be used also for period or hybrid analysis and to compute adjusted (weighted) estimates.
