It looks like the EventTime type is defined in Survival.jl. Glancing at the docs and source code it means “greater than 34”.
What Peter says - the point about time-to-event data is that it is right-censored if you still have some “live” observations (i.e. observations for which no event has taken place yet). The notation 34+ indicates that this observation has been observed for 34 time periods but no event has taken place, so the event time is greater than 34.
Got it. Thanks a lot. I am a beginner and learning things. Appreciate your response
