Dear all, I am having a (really) hard time getting pyears to work together with a ratetable to give me the number of expected events (deaths).
I have the following data: dos, date of surgery, as.Date dof, date of last follow-up, as.Date dos, date of surgery, as.Date sex, gender, as.factor (female,male) ev, event(death), 0= censored at time point dof, 1=death at time point dof Could someone please help. I am searching the web 5 days now and I cannot find any simple example that I can reproduce or fit to my needs. I have managed to get the patient years the conventional way: I use pyears to tcut the follow up time by age and year of surgery, and by sex. Then I do cross multiplication with the life tables I have obtained and customized. I have seen that the use of a ratetable together with the pyears function can produce the expected deaths, but I have not been successful applying it to my data. Could someone please help me with the syntax?
