Abstract

this article, we present a new algorithm to compute the moments, product moments, variances and covariances of order statistics in skewed continuous distributions for any sample size. The algorithm is written using the Gauss-Legender quadrature algorithm of GAUSS mathematical and statistical system matrix programming language. The accuracy of the calculations was tested for the Gamma, Weibull, and the extreme value distributions. A nonlinear least squares approximation for the first moments of order statistics for the gamma, Weibull and extreme value distributions is also presented.
