An example to show covariance estimation with the Mahalanobis distances on Gaussian distributed data. For Gaussian distributed data, the distance of an observation to the mode of the distribution can be computed using its Mahalanobis distance: where and are the location and the covariance of the underlying Gaussian distribution. In practice, and are replaced by some estimates.
