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 :
  • tino 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
    TemplateBox[{EmpiricalDistribution, paclet:ref/EmpiricalDistribution}, RefLink, BaseStyle -> InlineFormula],...nonparametric distribution estimation
    TemplateBox[{EstimatedDistribution, paclet:ref/EstimatedDistribution}, RefLink, BaseStyle -> InlineFormula],...parametric distribution estimation
    SurvivalModelFit,functions for survival analysis
  • Properties of EventData can be obtained by specifying EventData[]["property"].
