“…Before applying any econometric technique to the data, such as regression analysis, it is necessary to determine the unit root or trend and coherence of data which may cause issues in the statistical inference of time series data (Su, Cai, et al, 2021;Su, Qin, Tao, Shao, et al, 2020;Umar, Su, Rizvi, et al, 2021). This study uses the Augmented Dickey-Fuller test (ADF) for unit root and the Zivot-Andrew (ZA) test, which is famous for scrutinizing the data stationarity of the time series with a structural break (Umar, Ji, Kirikkaleli, Shahbaz, et al, 2020;Umar, Ji, Kirikkaleli, et al, 2021). Table 3 exhibits the unit root test outcomes, which suggest that all the variables such as TOR, COVID-19, ER, and OIL have unit roots at a level.…”
