I understand that we can calculate the probability density function (PDF) by computing the derivative of the cumulative distribution formula (CDF), since the CDF is the antiderivative of the PDF. I get the intuition for that (integrals denote the area under a curve, which is the accumulated probability under the curve of continuous functions) The Gaussian kernel Everybody believes in the exponential law of errors: the experimenters, because they think it can be proved by mathematics; and the mathematicians, because they believe it has been established by observation (Lippman in [Whittaker1967, p. 179]). 3.1 The Gaussian kernel The Gaussian (better Gaußian) kernel is named after Carl Friedrich Gauß (1777-1855), a brilliant.

Gaussian quadrature 1 Gaussian quadrature In numerical analysis, a quadrature rule is an approximation of the definite integral of a function, usually stated as a weighted sum of function values at specified points within the domain of integration. (See numerical integration for more on quadrature rules.) An n-point Gaussian quadrature rule, named after Carl Friedrich Gauss, is a quadrature. Gauss{Hermite and generalized quadrature rules, wk can be expressed in terms of ˚(xk) and ˚0(xk); see (3.5) and (4.4). For su ciently large n, some of the quadrature weights take a value less than the smallest positive normalized oating-point number in double precision. In such circumstances, these quadrature weights and corresponding nodes do not contribute to the nal quadrature estimate.
