WebFinally, Cholesky is found to be markedly computationally faster than QR, the mean value for QR is between two and four times greater than Cholesky, and the standard deviation in computation times using Cholesky is about a third of that of QR. Key words. Least squares problems, QR decomposition, Choleksy decomposition, random ma-trix, statistics 1. WebTo generate a random vector with a given covariance matrix Q, look at the Cholesky decomposition of Q i.e. Q = L L T. Note that it is possible to obtain a Cholesky decomposition of Q since by definition the co-variance matrix Q is symmetric and positive definite. Now look at the random vector Z = L X.
