The performance of a screening programme depends on a number of parameters, which may need different types of information for their estimation. In this paper, two characteristics of interest, the sojourn-time distribution and the sensitivity, are considered, and estimation procedures, based on data which should be available from a mass screening programme, are proposed. The methods are applied to published data from the HIP breast cancer screening project, to which a negative exponential distribution for the sojourn-time distribution fitted better than the other families of distribution considered.
筛查项目的性能取决于多个参数，对这些参数进行估计可能需要不同类型的信息。本文考虑了两个感兴趣的特征，即停留时间分布和灵敏度，并基于大规模筛查项目应能获取的数据提出了估计程序。这些方法应用于来自HIP乳腺癌筛查项目的已发表数据，对于该项目，停留时间分布采用负指数分布比其他所考虑的分布族拟合得更好。
