Question: The factorial moment-generating function for any random variable W is the expected value of tw. Moreover dr/dtr E(tW)|t=1 = E[W(W 1)(W r +

The factorial moment-generating function for any random variable W is the expected value of tw. Moreover dr/dtr E(tW)|t=1 = E[W(W ˆ’ 1)ãƒ»ãƒ»ãƒ»(W ˆ’ r + 1)]. Find the factorial moment-generating function for a geometric random variable and use it to verify the expected value and variance formulas given in Theorem 4.4.1.
