Modeling seasonality: An extension of the HEGY approach in the presence of two structural breaks [PDF]

open access: yesPanoeconomicus, 2008
In this paper the HEGY testing procedure (Hylleberg et al. 1990) of analyzing seasonal unit roots is tried to be re-examined by allowing for seasonal mean shifts with exogenous break points. Using some Monte Carlo experiments the distribution of the HEGY

The Seasonal KPSS Test: Examining Possible Applications with Monthly Data and Additional Deterministic Terms

open access: yesEconometrics, 2015
The literature has been notably less definitive in distinguishing between finite sample studies of seasonal stationarity than in seasonal unit root tests. Although the use of seasonal stationarity and unit root tests is advised to determine correctly the
