Interval-censored data arise in a wide variety of research and application fields such as cancer and AIDS studies. In this paper, we study a log-linear regression model when data are subject to interval censoring. We use a U-statistic based on ranks to estimate regression coefficients and establish large sample properties of the estimator. We illustrate the performance of the proposed estimate with simulations and a numerical example.
区间删失数据出现在各种各样的研究和应用领域，如癌症和艾滋病研究。在本文中，我们研究了数据受到区间删失时的对数线性回归模型。我们使用基于秩的U统计量来估计回归系数，并建立估计量的大样本性质。我们通过模拟和一个数值例子来说明所提出估计量的性能。
