  1. WS denotes the weighted-symmetric statistic of Park and Fuller (1995). AIC and SBC denote Akaike information criterion and Schwarz Bayesian criterion, respectively. A maximum lag order of 8 is allowed in the computation of the ADF and WS statistics. The fraction of rejections is based on 5 % nominal level tests
