Abstract: The HEGY12 and HEGY4 modules computes Beaulieu & Miron (J. Econometrics, 1993) seasonal unit root tests for monthly and quarterly time series, with and without intercept, seasonal dummies, and/or trend. The procedures report a Lagrange Multiplier of order 1-12 and a Ljung-Box test for autocorrelation in the error term.
