public final class Moment_joint_negbinomial_from_upfactorial extends Object
Joint negative-binomial moments from joint upward-factorial moments.

Converts joint upward-factorial moments into the joint negative-binomial moments b-_(i_1,...,i_d) = E[prod_j nchoosek(N_j+i_j-1,i_j)] = f+_(i) / prod_j (i_j!).

      public static double[] moment_joint_negbinomial_from_upfactorial(double[] fp, int[] dims)
      Converts joint upward-factorial moments into joint negative-binomial moments.
      Parameters:
      fp - flattened joint upward-factorial moments in row-major order, of extent dims[0]*...*dims[d-1]
      dims - extents of the array, dims[j] = n_j+1
      Returns:
      flattened joint negative-binomial moments, same layout
