 ## Various properties of the covariance matrix
-For this demonstration, we use the ten largest likelihood samples from PE run. We calculate the difference of norms of $`Sigma(k)\Sigma^{-1}(k)`$ and I(k), where $`Sigma(k)`$ is reduced covariance matrix with a rank of k, and I(k) is the identity matrix with rank k. The norm is calculated using the Frobenius method.
