CensoringType

The censoring mechanism of a Surv response.

Usage

CensoringType

Each member corresponds to one of the Surv constructors and describes how incomplete observations are handled:

  • RIGHT: Classic right-censoring. All subjects enter at time 0, and some are lost before the event occurs (Surv.right()).
  • LEFT: Left-censoring. The event is known to have occurred before the observation time (Surv.left()).
  • INTERVAL: Interval-censoring. The event is known to lie within a time bracket (Surv.interval()).
  • COUNTING: Counting-process (start, stop] intervals with possible late entry and time-varying covariates (Surv.counting()).

A constructed response reports its censoring type through Surv(...).type, which is one of these values.
