BiweightMidvariance—Wolfram Language Documentation

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. WebNov 20, 2001 · The biweight location estimator is both resistant and robust of efficiency. Mosteller and Tukey recommend using the median for exploratory work where moderate efficiency in a variety of situations is adequate and the biweight in situations when high performance is needed. The biweight location estimate is defined as: how to show rounded numbers in excel

WebFeb 1, 2013 · The biweight mean and biweight standard deviation, working like a regular mean and standard deviation, can be applied to reduce the implications of outliers (Lanzante 1996): View Expanded where K stands for the total number of sites (or 3249 in the target study), S is the total time covered by each dataset, is the median of , is the … Webtune(#) is the biweight tuning constant. The default is 7, meaning seven times the median absolute deviation (MAD) from the median residual; see Methods and formulas. Lower tuning constants downweight outliers rapidly but may lead to unstable estimates (less than 6 is not recommended). Higher tuning constants produce milder downweighting.
