WebJul 15, 2024 · Statistical moments are obtained directly from generalized polynomial chaos expansion. This paper presents a novel distribution-based global sensitivity analysis based on the Kullback–Leibler divergence derived directly from generalized polynomial chaos expansion (PCE). The synergy between PCE and Gram–Charlier expansion is utilized … WebOct 1, 2001 · Gram–Charlier expansions allow for additional flexibility over a normal density because they naturally introduce the skewness and kurtosis of the distribution as parameters. However, being polynomial approximations, they have the drawback of yielding negative values for certain parameters.

The Gram–Charlier A series (named in honor of Jørgen Pedersen Gram and Carl Charlier), and the Edgeworth series (named in honor of Francis Ysidro Edgeworth) are series that approximate a probability distribution in terms of its cumulants. The series are the same; but, the arrangement of terms (and thus the … See more We examine a continuous random variable.
