Table 1. Original time-series (lag = 0) on rows and lagged variable on columns.
The diagonal, as well as correlations that are not significant (p > 0.05) are omitted from the table. We present each correlation along with the best lag for the column variable (round brackets) and its significance level: a (p < 0.05), b (p < 0.01), c (p < 0.001) (superscript).
