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 .

Details Details

	t_i	no censoring; event happens at
	{t_i,∞}	right censoring; event happens at some t where
	{-∞,t_i}	left censoring; event happens at some t where
	{t_i,min,t_i,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 :
{ n_i} events at

{n_i,r_i} events and right-censored events at

{n_i,r_i,l_i} events, right-censored events, and left-censored events at
The following event specifications can be used for :
t_i,{t_i,∞} left truncation; observable for

{-∞,t_i} right truncation; observable for

{t_i,min,t_i,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"].
