How does a correlation matrix work
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. WebA correlation matrix helps study the interrelations between two or more variables. It shows the correlation coefficient between all possible pairs of variables. Every cell of the matrix consists of a correlation coefficient. A correlation matrix is used in the analysis of multiple linear regression models.
