Table 4 Statistical description for the top 20 features from RF (zero-shift) model. Q1 and Q3 stands for the first and third quartiles. The minimum, first quartile, median, third quartile and the maximum of a variable are often used as an empirical distribution approximation. Note that a minimum of 0 refers to missing values.
