本文采用半参数方法考察香港自杀事件报告系统中报告延迟的分布。数据来源于一种正确的截断情况，即只有在特定时间之前登记的自杀案件才知道发生过;否则，即使发生过，也不记录在已知死亡档案中。结果表明，中毒相关自杀死亡的报告延迟时间比其他自杀方式更长。通过建立报告延迟函数的模型，建议采用Horvitz-Thompson型估计量来调整报告延迟，并为监测香港的自杀问题提供更及时的自杀发生率估计。根据这些分析，我们建议了一个合适的截数日期，以收集香港在过去一年发生并在此日期前呈报的自杀个案。版权所有（C）2004约翰威利父子有限公司。
This paper uses a semi-parametric method to examine the reporting delay distribution in suicides in Hong Kong reporting system. The data arise from a rightly truncated situation in which only suicide cases registered before a specific time are known to have occurred; otherwise they are not recorded in the known death files even if they have occurred. It is shown that the poisoning-related suicide deaths have a longer reporting delay than other suicide methods. By modelling the reporting delay function, a Horvitz-Thompson-type estimator is suggested to adjust for reporting delay and to provide a more timely estimate of the suicide incidences for monitoring the suicide problem in Hong Kong. Based on these analyses, we recommended a suitable cut-off date to collect suicide cases occurring in the previous year and reported before this date in Hong Kong.
