intervalcensurering
Interval censoring is a type of data censoring in survival analysis. Instead of observing the exact time of an event, such as a disease recurrence or equipment failure, we only know that the event occurred within a specific time interval. For example, a patient might be examined at fixed intervals, and if the event is not observed at one examination but is observed at the next, the event time is known to lie between these two examination times.
This contrasts with right censoring, where we only know that the event occurred after a certain observation
Analyzing interval censored data requires specialized statistical methods. These methods account for the uncertainty introduced by
The presence of interval censoring can arise in various fields, including medical research (e.g., periodic follow-up
