Webb5 juli 2024 · Random Matrix Theory tells us that the eigenvalues of a pure noise matrix follow the Marcenko-Pastur distribution. This result holds asymptotically when N → ∞ … Webb8 aug. 2024 · Correlation is a function of the covariance. What sets these two concepts apart is the fact that correlation values are standardized whereas covariance values are not. You can obtain the correlation coefficient of two variables by dividing the covariance of these variables by the product of the standard deviations of the same values.

Three sides define a triangle, meaning given three volatilities we can obtain the three correlations. This is especially relevant for calculating implied correlations from option prices, but that is a topic for another day. 2. Three angles do not define a triangle. Given three correlations, we cannot obtain the corresponding volatilities.
