Abstract
Let ξn be a sequence of independent, identically distributed random elements in a separable Banach space X, for which the CLTholds: the normalized sums (ξ1+...+ξn)/n1/2 converge weakly to the Gaussian random element ζ. It is proved that, under certain conditions on the distribution of ξ1 and on the measurable mappingf: X→ R1, the distribution of the random variable\(f\left( {\frac{{\xi _1 + ... + \xi _n }}{{\sqrt n }}} \right)\) converges in variation to the distribution of the variablef(ζ).
