Skewness for distances ≤100 km are shown for seven periods; “Factor” shows the average of the absolute value of the seven mean residuals. Colored values show position in the hierarchy of the GMPE as given by the factor column (red, rank one; green, rank two; and blue, rank three). Note: If skewness is less than −1 or greater than +1, the distribution is highly skewed; if skewness is between −1 and −1/2 or between +1/2 and +1, the distribution is moderately skewed; and if the skewness is between −1/2 and +1/2, the distribution is approximately symmetric.
