Biweight filter

WebIn 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. [1] Derivation [ edit] Webof the biweight density function and the sum of its orthonormal polynomi-als is particularly suitable when the length of the filter is rather short, say, between 5 to 23 terms, which are those often applied by statistical agencies. At the beginning and end of the sample period, the Henderson filter of
