Multivariate Joint Probability Function of Earthquake Ground Motion Prediction Equations Based on Vine Copula Approach

Figure 1

Pair plots of transformed uniform data for residuals of PSAs at vibration periods of 0.1, 0.2, 1.0, 2.0, and 4.0 sec. The lower trigonal panels are bivariate contour plots, scatter plots, and correlation coefficients (Kendall’s τ) on the upper panels and histograms on the diagonal panels.
