Differentiating with respect to λ the expressions on both sides of the equation
Derive the following recursion formula for the moments about the mean of the Poisson distribution:
For r = 1, 2, 3, . . .. Also, use this recursion formula and the fact that µ0 = 1 and µ1 = 0 to find µ2, µ3, and µ4, and verify the formula given for a3 in Exercise 5.35.
