Hospital data (Neter et al., 1996)

Description

Data on the logged survival time of 108 patients undergoing liver surgery, together with four potential explanatory variables. Data are composed of 54 observations plus other 54 observations, introduced to check the model fitted to the first 54. Their comparison suggests there is no systematic difference between the two sets. However by looking at some FS plots (Riani and Atkinson, 2007), we conclude that these two groups are significantly different
