2.9. Let X₁,..., Xn be n observations for which the joint density function f(x₁,...,xn) depends on an unknown parameter vector 0. Assuming that f is a smooth function of 0, show that: (a) E(Vlog fe (X₁,..., Xn)) = 0; (b) E( − ▼²1(0)) = Cov (▼ log fø (X₁,..., Xn)), where 1(0) denotes the log-likelihood function.
