Khmaladze-type graphical evaluation of the proportional hazards assumption

John O'Quigley

Biometrika, 2003, vol. 90, issue 3, 577-584

Abstract: Khmaladze-type goodness-of-fit tests are based on transforming an appropriate empirical process to one with a known large-sample distribution. Using Donsker's theorem, together with a theorem for proportional hazards generalising a theorem of Xu & O'Quigley (1999), we indicate how to construct a Khmaladze-type graphical test for evaluating the proportional hazards assumption. An illustration is given in which a partially proportional hazards model can be seen to provide a noticeably improved fit over a fully proportional hazards model.
