These functions estimate the latent factors of a given matrix, no matter it is highdimensional or not. It tries to first estimate the number of factors using bicrossvalidation and then estimate the latent factor matrix and the noise variances. For more information about the method, see Art B. Owen and Jingshu Wang 2015 archived article on factor model (http://arxiv.org/abs/1503.03515).
