Sequential testing of duration data: the case of the Pennsylvania ‘reemployment bonus’ experiment
通过回顾宾夕法尼亚州“再就业奖金”实验，展示了如何在数据积累过程中进行序贯检验，以便在得出明确统计结论后及时终止实验，对从事实验设计和数据分析的经济学者有参考价值。
Abstract Cost considerations and the need to report the results promptly make it desirable to examine data as it accumulates and to terminate an experimental study as soon as definite statistical conclusions can be drawn. These ideas are illustrated in a retrospective analysis of the Pennsylvania ‘Reemployment Bonus’ experiment. Recently developed large‐sample theory for a variety of sequentially computed score processes of time‐to‐event (duration) data with staggered entry enables one to construct stopping boundaries of a prescribed level of significance. The gains from the use of sequential methodology appear to be worth while. Copyright © 2000 John Wiley & Sons, Ltd.
