High dimensional linear regression
http://robotics.stanford.edu/~ormoneit/research/node1.html WebIn this work, we incorporate matrix projections into the reduced rank regression method, and then develop reduced rank regression estimators based on random projection and orthogonal projection in high-dimensional multivariate linear regression model. We propose a consistent estimator of the rank of the coefficient matrix and achieve …
