基于残差分析的图解方法被认为是用于设置频繁使用的考克斯（1972）回归模型和用于Andersen-Gill（1982）对该模型的推广。我们从Barlow和普伦蒂斯（1988）提出的一类基于鞅的残差开始。这些残差和/或它们的变换对于研究协变量的函数形式、比例风险假设、每个受试者对β的估计的杠杆作用，以及缺乏对给定对象的模型拟合。
Graphical methods based on the analysis of residuals are considered for the setting of the highly-used Cox (1972) regression model and for the Andersen-Gill (1982) generalization of that model. We start with a class of martingale-based residuals as proposed by Barlow and Prentice (1988). These residuals and/or their transforms are useful for investigating the functional form of a covariate, the proportional hazards assumption, the leverage of each subject upon the estimates of .beta., and the lack of model fit to a given subject.
