Id k that extends past the broken line, reject the null hypothesis that k = 0 at 5% level of significance. Otherwise, do not reject the null hypothesis" (Danao). In this particular tests, the result for BARC, VOD and FTALLSH show that we do not reject the null hypothesis that k = 0. But for the GSK graph, the result is opposite. We have necessary proof to reject the null hypothesis. Decision Rule: "If the absolute value of the ADF Test Statistic is less than the value of the McKinnon Critical Values at the chosen level of significance, then the series has a unit root and is therefore non-stationary.
