Webcorrelation. correlation is an easystats package focused on correlation analysis. It’s lightweight, easy to use, and allows for the computation of many different kinds of correlations, such as partial correlations, Bayesian correlations, multilevel correlations, polychoric correlations, biweight, percentage bend or Sheperd’s Pi correlations ... WebAn analysis of the correlation between the returns of different securities is of fundamental importance in many areas of finance, such as portfolio optimisation. The most commonly used measure of correlation is the Pearson correlation coefficient; however, this suffers from several problems when applied to data from the real world. We propose an …

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. WebJun 25, 2007 · Tukey's biweight is a type of M-estimate, a class of estimators which has been used in robust correlation estimates (for example, Mosteller and Tukey defined the cob and Wilcox defined the percentage bend correlation .)

In statistics, biweight midcorrelation (also called bicor) is a measure of similarity between samples. It is median-based, rather than mean-based, thus is less sensitive to outliers, and can be a robust alternative to other similarity metrics, such as Pearson correlation or mutual information.
