Principal Components and Long Run Implications of Multivariate Diffusions

Chen, Xiaohong; Hansen, Lars Peter; Scheinkman, Jose - Cowles Foundation for Research in Economics, Yale University - 2009

We investigate a method for extracting nonlinear principal components. These principal components maximize variation subject to smoothness and orthogonality constraints; but we allow for a general class of constraints and multivariate densities, including densities without compact support and...
