e/Higher-order statistics

Information
has gloss	eng: Higher-order statistics (HOS) are descriptive measures of, among other things, qualities of probability distributions and sample distributions, and are, themselves, extensions of first- and second-order measures (such as the mean, variance, autocorrelation function, and power spectrum) to higher orders. Skewness and kurtosis are examples of this. Arguably, the estimates of coefficients and associated significance tests, in a regression analysis, of terms for effects higher than quadratic could be included here, too.
