Abstract
A class of goodness of fit tests for the proportional hazards regression model is proposed. The alternatives considered permit the parameters of the model to vary as step functions with time. Restricting the type of step function allowed gives rise to tests against more specific alternatives. Computational details are given.
摘要
提出了一类用于比例风险回归模型的拟合优度检验。所考虑的备择假设允许模型参数随时间呈阶梯函数变化。限制允许的阶梯函数类型会产生针对更具体备择假设的检验。给出了计算细节。
