Please some one give an example code. Thanks in advance. The form of the function you want to fit to this depends on what kind of distribution it is. Two examples of asymmetric distributions that might be good are the Weibull distribution, and a reversed lognormal distribution.

Hermite-Gauss Quadrature -- from Wolfram MathWorld

WebMar 24, 2024 · Hermite-Gauss quadrature, also called Hermite quadrature, is a Gaussian quadrature over the interval (-infty,infty) with weighting function W(x)=e^(-x^2) (Abramowitz and Stegun 1972, p. 890). The abscissas for quadrature order n are given by the roots x_i of the Hermite polynomials H_n(x), which occur symmetrically about 0. WebGauss-Hermite (physicist’s) quadrature. Compute the sample points and weights for Gauss-Hermite quadrature. The sample points are the roots of the nth degree Hermite polynomial, H n ( x). These sample points and weights correctly integrate polynomials of degree 2 n − 1 or less over the interval [ − ∞, ∞] with weight function w ( x ...
