摘要

我们提出了一类新的生存模型的时间到事件的数据与治愈分数。这个新模型是对推广时间治愈率模型的扩展。进一步，我们将模型推广到回归模型，以评估协变量对治愈分数的影响。采用期望最大化算法对模型参数进行估计。为了验证所提出的模型和计算算法，进行了仿真研究。该方法使用一个真实的巴西银行个人贷款组合数据集来说明。

A New Class of Cure Rate Survival Models: Properties, Inference and Applications

We propose a new class of survival models for time-to-event data with a cure fraction. This new model is an extension of the promotion time cure rate model. Furthermore, we extend the model to the regression model to evaluate the effect of covariates in the cure fraction. An expectation-maximization algorithm is adopted for estimating the model parameters. A simulation study is conducted in order to assess the proposed model and the computation algorithm. The methodology is illustrated using a real Brazilian bank personal loan portfolio data set.
