我们研究了一个测试，比较完整的阿伦附加危险模型和变点模型，并提出如何估计变点模型的参数。我们还研究了无变点效应的测试。这两个检验都提供了大样本属性，并应用重采样方法来获取 p 值。通过模拟研究评估所提出的推理程序和估计器的有限样本属性。该方法进一步应用于有关心肌梗塞的数据集。
We study a test comparing the full Aalen additive hazards model and the change-point model, and suggest how to estimate the parameters of the change-point model. We also study a test for no change-point effect. Both tests are provided with large sample properties and a resampling method is applied to obtain p-values. The finite-sample properties of the proposed inference procedures and estimators are assessed through a simulation study. The methods are further applied to a dataset concerning myocardial infarction.
