Censoring

Censoring
represents a censored event time t with censoring c.
Censoring
represents a vector of censored event times with censoring c.
Censoring
represents a vector of event times with corresponding censoring .
  • The following censoring types c can be used in Censoring:
0, None{t,t}no censoring
1, Right{t,∞}right-censoring
-1,Left{-∞,t}left-censoring

Convert a right-censored observation to interval notation:
Alternatively, use Right:
Work with left-censored observations:
Alternatively, use Left:
The observation is unchanged in the absence of censoring:
You can also specify no censoring as None:
Thread a single censoring indicator over a list of events:
Use a mix of censoring indicators:
Interval-censored observations are converted as well:
A dataset of length 2 is treated as a single interval-censored observation:
One right-censored observation results in:
If two observations were intended, use two indicators:
