WebOct 11, 2010 · I present a parametric, bijective transformation to generate heavy tail versions Y of arbitrary RVs X ~ F. The tail behavior of the so-called 'heavy tail Lambert W x F' RV Y depends on a tail parameter delta >= 0: for delta = 0, Y = X, for delta > 0 Y has heavier tails than X. For X being Gaussian, this meta-family of heavy-tailed distributions … WebGaussianize data using various methods. This class is a wrapper that follows sklearn naming/style (e.g. fit (X) to train). In this code, x is the input, y is the output. But in the …
