WebCorrelation coefficients, returned as a matrix. For one matrix input, R has size [size (A,2) size (A,2)] based on the number of random variables (columns) represented by A. The diagonal entries are set to one by convention, while the off-diagonal entries are … plotmatrix(X) is the same as plotmatrix(X,X) except that the subaxes along the … corrplot computes p-values for Pearson’s correlation by transforming the … The matrices RL and RU give lower and upper bounds, respectively, on each … Correlation Bounds. Create a normally distributed, random matrix, with an … WebAlong with the Pearson correlation as a baseline, I was thinking to include following more robust measures: Spearman's ρ Percentage bend correlation (Wilcox, 1994, [1]) Minimum volume ellipsoid, minimum covariance determinant ( cov.mve / cov.mcd with the cor=TRUE option) Probably, the winsorized correlation
