On the Convergence of the Chi Square and Noncentral Chi Square Distributions to the Normal Distribution

open access: yesIEEE Communications Letters, 2013
A simple and novel asymptotic bound for the maximum error resulting from the use of the central limit theorem to approximate the distribution of chi square and noncentral chi square random variables is derived. The bound enables the quick calculation of the number of degrees of freedom required to ensure a given approximation error, and is ...
