D Sporsmal 1 1 poeng Suppose X1, X2, . .., Xn are iid random variables with PDF/PMF f(x; 0). Then IIt=1 f(X;; 0) is the O log-likelihood function likelihood function O Fisher information O score function D Sporsmal 2 1 poeng Suppose that I(0) is the log-likelihood function for some statistical model. For 0 to be a MLE, we require that O 3 1(0) # 0 and 292 1(0) = 0 O 2 1(0)
