BUILT-IN MATHEMATICA SYMBOL

# EventData

EventData[{e1, e2, ...}]
represents event data with explicitly specified censoring .

EventData[{e1, e2, ...}, {ci1, ci2, ...}]
represents event data with censoring indicators .

EventData[{e1, e2, ...}, {cc1, cc2, ...}]
represents event data with censoring counts .

EventData[{e1, e2, ...}, cspec, {tr1, tr2, ...}]
represents event data with censoring and truncation .

## DetailsDetails

• EventData augments data with censoring and truncation information.
• The following event specifications can be used for :
•  ti no censoring; event happens at {ti,∞} right censoring; event happens at some t where {-∞,ti} left censoring; event happens at some t where {ti,min,ti,max} interval censoring; event happens at some t where
• The following censoring indicators can be used for :
•  0, None {t,t} no censoring 1, Right {t,∞} right censoring -1,Left {-∞,t} left censoring
• The following count specifications can be used for :
•  { ni} events at {ni,ri} events and right-censored events at {ni,ri,li} events, right-censored events, and left-censored events at
• The following event specifications can be used for :
•  ti,{ti,∞} left truncation; observable for {-∞,ti} right truncation; observable for {ti,min,ti,max} interval truncation; observable over
• EventData can be used in statistics functions including:
•  Mean, Variance, ... descriptive statistics functions nonparametric distribution estimation parametric distribution estimation SurvivalModelFit, ... functions for survival analysis
• Properties of EventData can be obtained by specifying EventData[...]["property"].
• A list of available properties can be obtained using EventData[...]["Properties"].
• EventData has the following properties:
•  "CensoringIndicators" censoring indicators "CensoredData" censored event intervals in the form "EmpiricalPDF" event locations and corresponding estimated weights "InputData" input event specification "MetaInformation" list of meta information rules "TruncationIntervals" truncation intervals "CensoringType" most general type of censoring present "TruncationType" most general type of truncation present
