Using Events From Dropouts in Nonparametric Survival Function Estimation With Application to Incubation of AIDS
利用退出研究后的事件估计非参数生存函数:艾滋病潜伏期应用
Often postdropout responses (PDR) in study dropouts are identified from death/disease registries or other medical records. If ail dropout is random, then use of postdropout responses while censoring other subjects at date of dropout (CDO/PDR) will bias nonparametric survival probability estimates downward. Censoring all individuals at the last date of study contact, ignoring postdropout information (CDO) will produce unbiased nonparametric survival estimates. As onset of the…
