Wishart and Anti-Wishart random matrices
We provide a compact exact representation for the distribution of the matrix elements of the Wishart-type random matrices AA, for any finite number of rows and columns of A, without any large N approximations. In particular we treat the case when the Wishart-type random matrix contains redundant, non-random information, which is a new result. This representation is of interest for a procedure o...
متن کاملNonintersecting Brownian interfaces and Wishart random matrices.
We study a system of N nonintersecting (1+1)-dimensional fluctuating elastic interfaces ("vicious bridges") at thermal equilibrium, each subject to periodic boundary condition in the longitudinal direction and in presence of a substrate that induces an external confining potential for each interface. We show that, for a large system and with an appropriate choice of the external confining poten...
متن کاملNon-Hermitean Wishart random matrices (I)
A non-Hermitean extension of paradigmatic Wishart random matrices is introduced to set up a theoretical framework for statistical analysis of (real, complex and real-quaternion) stochastic time series representing two ‘remote’ complex systems. The first paper in a series provides a detailed spectral theory of non-Hermitean Wishart random matrices composed of complex valued entries. The great em...
متن کاملSparse principal component analysis via random projections
We introduce a new method for sparse principal component analysis, based on the aggregation of eigenvector information from carefully-selected random projections of the sample covariance matrix. Unlike most alternative approaches, our algorithm is non-iterative, so is not vulnerable to a bad choice of initialisation. Our theory provides great detail on the statistical and computational trade-of...
متن کاملAspects of pseudorank estimation methods based on the eigenvalues of principal component analysis of random matrices
Nowadays, analytical instruments that produce a data matrix for one chemical sample enjoy a widespread popularity. However, for a successful analysis of these data an accurate estimate of the pseudorank of the matrix is often a crucial prerequisite. A large number of methods for estimating the pseudorank are based on the eigenvalues obtained from principal component analysis (PCA) . In this pap...
