摘要 针对复发事件数据协变量的重要作用,建立含有协变量的复发事件变点模型,考虑协变量作用于强度率函数的情形。对于此模型,使用最大似然方法得到变点及各参数估计,并得到了变点估计的相合性。最后对于同时存在待估参数和待估变点的似然函数,采用最速上升法进行了数据模拟。 Recurrent event data is widely applied to biostatistics ,clinical medicine ,industry reliability and insurance actuarial .The model of change -points in recurrent events has certain significance in the abstract and foreground in the application .We consider the change -points with covariates in recurrent events and adopt MLE to estimate the change - points and parameters . Moreover we illustrate the consistence of the estimators .
