Dear all,
I am using strs to estimate relative survival and unless I make a mistake, I
notice that excess mortality rate are allowed to be negative and therefore
cumulative relative survival (ederer I, II or Hakulinen) is allowed to
increase.
Although I find interesting to have an estimation of a negative excess
mortality rate, I would prefer cumulative relative survival to stay constant
rather than increase when the number of deaths is smaller than expected
during the interval (like in strel). Is there a way to parameterise strs
this way?
Thank you for your help
