Deviations of discrete distributions and a question of Móri


  • Berenhaut, Kenneth S.
  • Baxley, John V.
  • Lyday, Robert G.


In this note, we consider a question of Móri regarding estimating the deviation of the kth terms of two discrete probability distributions in terms of the supremum distance between their generating functions over the interval [0,1]. An optimal bound for distributions on finite support is obtained. Properties of Chebyshev polynomials are employed.
