WebThis function performs the Engle-Granger two-step cointegration test on all possible combinations of time series in a given dataset. It extracts test statistic and p-values from the Augmented Dickey-Fuller test on the residuals of each pair of time series. WebThe p-value is a probability that measures the evidence against the null hypothesis. Lower probabilities provide stronger evidence against the null hypothesis. To determine whether to difference the data, compare the test statistic to the critical value or the p-value to your significance level.
