WebNice question! The plan is to use the definition of expected value, use the formula for the binomial distribution, and set up to use the binomial theorem in algebra in the final step. We have E(e^(tx)) = sum over all possible k of P(X=k)e^(tk) = sum k from 0 to n of p^k (1-p)^(n-k) (n choose k) e^(tk) WebRandom component - The distribution of the response variable is assumed to be binomial with a single trial and success probability \(E(Y)=\pi\). Systematic component - \(x\) is the explanatory variable (can be continuous or discrete) and is linear in the parameters.
