title: Exact significance levels for Hewitt's test for seasonality.
abstract: Hewitt proposed an easily computed test for seasonality in ranked monthly data. This paper provides a tabulation of the exact distribution of the test statistic, which previously could be estimated only from simulated data. The use of this test when ties may occur in the data is also discussed.
