The sample data file Bladder contains data on bladder tumor recurrences from the Veteran’s Administration Co-operative Urological Research Group. See Andrews and Herzberg (1985, table 45). All patients presented with superficial bladder tumors, which were removed upon entering the trial. Each patient was then assigned to one of three treatment groups: placebo pills, pyridoxine (vitamin B6) pills, or periodic chemotherapy with thiotepa. The following analysis of tumor recurrence explores the progression of the disease, and whether there is a difference among the three treatments.
