[Question] Estimate 1-year survival based on 4-year survival assuming equal survival across time
I have a survival estimate over a 4-year time period, 35% survival. However, what I need is an estimate of survival over 1-year. I do not have any more specific data, just total population at time 0 (162) and total population at time 4 (57). If I assume that survival is equal across years, is it possible to estimate survival for 1 year? I am working in R, if that's needed.
