I have a medical data set that has all the following cases:

  • Right-censored
  • Left-censored
  • Interval-censored
  • Delayed-censored and
  • truncated-data.

I am trying to fit this data with CoxPH function in survival package in R. So my question, is there any consideration I have to take when I feed the data to Cox model, or just use the data as is.
