In this study, the 5% significant level is applied in the tests.

WebbThe statistical properties of most estimators in time series rely on the data being (weakly) stationary. Loosely speaking, a weakly stationary process is characterized by a time-invariant mean, variance, and autocovariance. In most observed series, however, the presence of a trend component results in the series being nonstationary.
