Abstract: A statistical procedure for detection of periodic autocorrelation in time series data is presented. Intuitively, the probability of a zero‐crossing at time t should be inversely related to the correlation between observations at times t and t− 1. Explicit formulas displaying this inverse relationship are given for mean‐zero periodically correlated time series with certain distributional structures. A test statistic based on this relationship is developed. This testing method provides a robust approach to detection of periodic autocorrelation. Analysis of simulated and actual data sets illustrates the usefulness of the proposed method.
