Simulated Data

Description

Simulated Interval-censored data

Format

A data frame with 100 observations on the following 3 variables.

L

the left endpoints of the censoring interval

R

the right endpoints of the censoring interval

Z

a continuous covariate

Details

The value R = NA means that the observation is right censored (occurs 2 times). If L = NA, then the observation is left censored (occurs 26 times). An observation with R = L means that the time of occurence of the event is known exactly (occurs 3 times).
