lungdata: 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.
