Randomization Tests in Econometrics
介绍随机化检验在计量经济学中的原理、优势与陷阱，帮助研究者理解这种由计算机革命推动的争议性方法，并判断其适用性。
Numerous shufflings of data produce a distribution of test-statistic values that can be used to assess the degree to which the test-statistic value produced by the actual data is unusual. Because this controversial randomization-testing methodology, made practical by the computer revolution, has begun to appear in applied econometric studies, econometricians should become familiar with its mechanics, rationale, and interpretation, all of which are quite different from the status quo. This article exposits randomization tests in an econometric context, discusses their advantages, and alerts practitioners to pitfalls.
