摘要：The paper considers a group of patients suffering from leukemia B non-small lung cancer. Suchpatients are generally suggested to undergo for either radiotherapy or chemotherapy followed by radiotherapy.The objective of the paper is to compare the two therapies based on survival functions of the patients assumingWeibull survival model for each therapy. The paper further examines the feasibility of a subfamily of Weibullmodel, namely the exponential distribution, for a date set available from a clinical trial experiment. Thisfeasibility is judged based on Bayes information criterion by comparing the Weibull model with its subfamily.The model compatibil ity study with the dat a based on posterior p-values has also been given to ensure thesuita bility of the two models. Finally, the recommendations are made accordingly
