% Here are two versions of the Stanford Heart Transplant data. The % first is from Kalbfleisch and Prentice (first edition) while the second is % from from Crowley and Hu. The two versions are slightly different, and the % X matrix is sufficiently ill-conditioned that the variations make a big % difference. Thanks to Terry Therneau for noticing the problems and % providing both data sets. % % % Note: Here the Kalbfleisch and Prentice data is used. % % % Information about the dataset % CLASSTYPE: numeric
