Expected value of n^q when n follows a Poisson law.
A positive integer vector.
A positive number.
The expectation of n^q when n follows a Poisson ditribution has been derived by Grassberger (1988).
A vector of the same length as
x containing the transformed values.
The function is computed using the
Its value is 0 for n-q+1<0.
