WebOct 8, 2024 · Correlation Matrix: It is basically a covariance matrix. Also known as the auto-covariance matrix, dispersion matrix, variance matrix, or variance-covariance matrix. It is a matrix in which i-j position defines the correlation between the ith and jth parameter of the given data-set. It is calculated using numpy ‘s corrcoeff () method.
