Curve of The curve of α(e) Obtained from the Gaussian Mixture Model from Real Dataα(e) is monotone decreasing in the area of [-4, 0.5], which agree with the existing knowledge.
However, the curve unexpectedly ramps up (the broken line)due to the heavier tail
of the positive component. To resolve this problem, we simply fix the curve to be
a constant. This heuristic is simple but works well in practice. The solid line in
Figure 4 visualizes α(e) with this heuristic
