Hello,
I am having problems solving the following question:
Let the random variable X have a Poisson distribution with parameter [lambda]. Show that for every n>=1 one has E(X^n) = [lambda]E[(X +1)^(n-1)]: Note that, using this formula, we can nd E(X);E(X2), . . .recursively.
I have no idea what to do... Please help
-Thanks
