Convergence of a matrix
WebJan 5, 2011 · Given a probability distribution in ℝ n with general (nonwhite) covariance, a classical estimator of the covariance matrix is the sample covariance matrix obtained from a sample of N independent points. What is the optimal sample size N = N ( n) that guarantees estimation with a fixed accuracy in the operator norm? WebWhether a particular method will work depends on the iteration matrix B = M -1 N. In fact, in general, B completely determines the convergence (or not) of an iterative method. In particular, the initial guess generally has no effect on whether a particular method is convergent or on the rate of convergence.
