Scatter plots of the pairs for all the tests of the (a) 2D and (b) 3D testing sets, and (c) real data set, overlaid on the SVS selection regions described in Figure 4 for (left) SVS-2D, (middle) SVS-3D, and (right) SVS-2D&3D. We note that the three versions of SVS selected SBA as the most appropriate method for nearly all tests of the real data set (c).
