Biweight correlation

WebThe biweight midcorrelation is a measure of similarity between samples. It is given by: where ζ x x is the biweight midvariance of x , ζ y y is the biweight midvariance of y, and ζ x y is the biweight midcovariance of x and y. Input arrays for the two variables. x and y must be 1D arrays and have the same number of elements. Web统计学英文名词-豆丁网总结统计学专用英文名词,对统计学相关英文文献的阅读和学习起到不可或缺的作用。

Creates diagnostic bivariate quelplot ellipses (bivariate boxplots) using the method of Goldberg and Iglewicz (1992). The output can be used to check assumptions of bivariate normality and to identify multivariate outliers.
