This example is based on a dataset from "Modern Applied Statistics with S" by Venables and Ripley, Fourth Edition, Springer, 2002. (Page 357) Note that the data is also available in the free statistical analysis tool R, the dataset '''gehan''' under the library '''MASS'''.
 In this survival dataset, there are two types of treatment groups, denoted by '''6-MP''' and '''control'''.
