摘　　要：基于MM算法改进了加权秩估计求解,得到模型参数的相合估计。结合自助法得到参数的区间估计,模拟验证了方法的有效性。将此模型运用到艾滋病潜伏期数据中,发现儿童群体年龄和艾滋病潜伏期呈负相关。MM algorithm is applied to improve the weighted rank estimation to get the consistent prediction of the model parameters.The interval estimation of the parameters with Bootstrap is used to verify the method.The model is introduced to the data of AIDS incubation period and it is suggested that the age of children is negatively correlated with the period.

关 键 词：双截断 MM算法 自助法 艾滋病潜伏期
