The linear shrinkage estimator of the population covariance matrix is computed by shrinking the sample covariance matrix towards the identity matrix based on a shrinkage factor. Note that the eigenvalues of the population covariance matrix estimate are not the same as the linear shrinkage estimates of population eigenvalues. Details in referenced publication.
