Lung cancer data

Description

A case 1 interval-censored data set first presented in Hoel and Walberg (1972) and can be found in Sun (2006, page 6). In the study, 144 male RFM mice were raised under two conditions: conventional environment (96 mice) and germfree environment (48 mice). Each mouse was "sacrificed" at a random time to see if it had lung tumors. Time was measured in days.

Usage

data(lungdata)

Format

A matrix with 144 rows and 4 columns. Each row (L, R, status, treatment) corresponds to a mouse in the study.

L

left-points of observed intervals

R

right-points of observed intervals

status

censorship indicator: 1=left-censor and 0=right-censor

treatment
