How does a correlation matrix work
WebJun 21, 2024 · I have a somewhat large matrix (685 rows by 12 columns) that I need to take the correlation coefficient over every ten rows of specific columns that I need to specify. Any help would be appreciated. WebWhen a matrix has this mirror-image quality above and below the diagonal we refer to it as a symmetric matrix. A correlation matrix is always a symmetric matrix. To locate the correlation for any pair of variables, find the value in the table for the row and column intersection for those two variables.
