FORMALIZED DATA SNOOPING BASED ON GENERALIZED ERROR RATES
回顾了统计文献中控制广义错误率的方法，用于解决同时进行多个假设检验时如何决定拒绝哪些假设的问题，并通过模拟和实证应用展示了这些方法在模型选择中的适用性。
It is common in econometric applications that several hypothesis tests are carried out simultaneously. The problem then becomes how to decide which hypotheses to reject, accounting for the multitude of tests. The classical approach is to control the familywise error rate (FWE), which is the probability of one or more false rejections. But when the number of hypotheses under consideration is large, control of the FWE can become too demanding. As a result, the number of false hypotheses rejected may be small or even zero. This suggests replacing control of the FWE by a more liberal measure. To this end, we review a number of recent proposals from the statistical literature. We briefly discuss how these procedures apply to the general problem of model selection. A simulation study and two empirical applications illustrate the methods.We thank three anonymous referees for helpful comments that have led to an improved presentation of the paper.
