Zhou Min Estimator augmentation with applications in. The eigenvectors of sample covariance matrices in high-dimensional settings raise questions on the value of such two-stage methods (see, for example, johnstone and lu, 2009)., while a number of techniques to model the data distribution and thus to esti- mate the selectivity are known for one- and low-dimensional data spaces, this is still an unsolved problem for data spaces of medium to high dimensionality..
