Method of Moments Estimation of High-Dimensional Covariance Using a Parametric Model

Iain M. Johnstone, Yuchen Wu, Ran Xie

We propose method-of-moments estimators for the eigenvalues of variance component covariance matrices in multivariate mixed effects models. Assuming a parametric form for the eigen…
