a colleague asked me if the central moments of a binomial distribution B(n;p), considered as polynomials in n and p, have a particular name. I found discussions of these polynomials, especially by Romanovsky (Biometrika 15, 1923, 410--412), and, in the context of Bernshtein polynomials, by G.G. Lorentz (in his book on Bernshtein polynomials of 1953). Up to he fifties, however, as it seems, these polynomials had not obtained a special name.
Did these polynomials obtain a name since then? Are there any relations to Appell or Sheffer polynomials?
