The data comes from various sources, which are detailed in the paper in Table 2.
For the variables in the first and third groups, we apply logarithms and first differences of logarithms. For the financial series in the second group, two measures are calculated: logarithmic returns and the Parkinson estimator of variance. We use the following symbols to denote these transformations: ln, s_ln, delta, r, and v for logarithm, signed logarithm, first difference of logarithms, logarithmic return, and variance, respectively.
