Time Dependent Cox Model
I am having trouble formatting some survival data to use in a time dependent
cox model. My time dep. variable is habitat and I have it recorded for every
day (with some NAs). I think it is working properly except for calculating
the death.time. This column should be 1s or 0s and as I have it only
produces 0s. Any help will be greatly appreciated.
