这项研究的动机是艾滋病病例诊断日期和报告日期之间的时间差，这导致了关于疫情的不完整数据。已经制定了一种最大可能性程序，以调整实际诊断的艾滋病病例数量，以推迟报告。如果假设一个描述过去和未来事件的参数函数，则可以同时估计其参数和对报告延迟的调整。使用的数据来自位于巴黎的世卫组织艾滋病合作中心。讨论了与数据收集有关的实际问题。
This study is motivated by the time lag between date of diagnosis of AIDS cases and date of reporting, which results in incomplete data about the epidemic. A maimum likelihood procedure has been developed to adjust the actual numbers of diagnosed AIDS cases for reporting delay. If a parametric function for describing past and future incidence is assumed, its parameters and the adjustment for reporting delay can be estimated simultaneously. Data from the WHO Collaborating Centre on AIDS, Paris, are used. Practical problems related to data collection are dealt with.
