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] WebJul 26, 2002 · The biweight midvariance estimator is both resistant and robust of efficiency. Mosteller and Tukey recommend using the MAD or interquartile range for exploratory work where moderate efficiency in a variety of situations is adequate. The biweight midvariance estimator can be considered for situations where high … health insurance plans in virginia

WebThe biweight is an M-estimator that satisfies the definitions given above and the weight is calculated as: weight = {1-(u^2)/4.685^2}^2 when abs(u) <= 4.685 weight = 0 when … WebThis function implements biweight midcorrelation calculation (see references). If y is not supplied, midcorrelation of columns of x will be calculated; otherwise, the midcorrelation between columns of x and y will be calculated. Thus, bicor (x) is equivalent to bicor (x,x) but is more efficient. WebThen, we filter out non-informative correlation pairs using the 'half-thresholding' strategy and calculate the differential coexpression value of gene, The experimental results on … health insurance plans in puerto rico
