Spearman Rank Correlation It calculates the Spearman rank correlation coefficient from 2 or more data sets, and the associated t-test and p-values. The code is adapted with major changes from the Numerical Recipes book (http://www.nr.com/)Example:>> x = [1 2 3 3 3]';>> y = [1 2 2 4 3; rand(1,5)]';>> [r,t,p] = spear(x,y)>>...

Quick Correlation Coefficients The correlation coefficient (commonly noted by the Greek letter rho, ?) measures the degree to which two sets of numbers are related. The correlation coefficient can range from -1.000 to +1.000 with a 0 indicating that there is no relation between the two sets. A 'slider' data entry option...

IPN_voxelGraph 1) How to compute a Pearson correlation coefficient in MATLAB? The idea is a simple fact in math: for two standardized variables (0 mean and 1 std), the correlation is equivalent to their inner product. Thus, for two large sample matrices X and Y, the sample correlation matrix is R=X'Y/(n-1),...
