摘要
本文研究了带有辅助协变量的分组相关失效时间数据的边际风险模型,获得了未知参数的伪偏似然估计,证明了所得估计的相合性和渐进正态性.
In this article, we consider an inference procedure for clustered correlated failuretime with auxiliary covariate information. We propose an estimated pseudo partial likelihood esti-mator under the marginal hazard model framework and develop the asymptotic properties for theproposed estimator.
