WebbUnless they are somehow dependent, averaging many rank one matrices provides a full rank matrix. If your stochastic process is additionally stationary and ergodic, you can replace the ensemble average by an average over time, using subsequent realizations $\mathbf x_i$ via $\sum \mathbf x_i \mathbf x_i^{\rm T}$. Webb11 nov. 2016 · Spearman’s rank correlation is a robust alternative for the standard correlation coefficient. Using ranks instead of the actual values of the observations, the impact of outliers remains limited. In this paper, we study an estimator based on this rank correlation measure for estimating covariance matrices and their inverses.
