Unified extension of variance bounds for integrated Pearson family (1110.0090v2)
Published 1 Oct 2011 in math.PR
Abstract: We use some properties of orthogonal polynomials to provide a class of upper/lower variance bounds for a function $g(X)$ of an absolutely continuous random variable $X$, in terms of the derivatives of $g$ up to some order. The new bounds are better than the existing ones.
