讨论了当反应变量为患者的生存时间时，识别各种预后因素的作用的问题。Morgan和Sonquist的构造相似风险组的方法是有用的，并描述了一个实现该方法的算法，该方法适用于带有截尾观测的生存时间数据。给出了它在两组医学数据中的应用实例，这两组数据源于肾移植后的预后研究和I期皮肤恶性黑色素瘤的治疗。
The problem of identifying the role of various prognostic factors when the response variable is the patient's survival time is discussed. Morgan and Sonquist's approach of constructing groups at similar risk is useful and an algorithm which implements the method for survival time data with censored observations is described. Examples of its application to two sets of medical data are given, arising from studies of prognosis following renal transplantation and treatment for stage I malignant melanoma of the skin.
