Assume Y1, ... , Yn are IID continuous variables with PDF f(yi;
θ), where f is dependent on a parameter θ.
Complete the following:
a) Derive the likelihood, L(θ), and the log-likelihood, l(θ), in
terms of the function f.
b) Find dl/d(theta) in terms of f(yi; θ) and df/d(theta). Note
that dl/d(θ) is usually referred to as the score function.
c) Show that E[dl/d(θ)]= 0. Hint: you can use without proof the
following: ∫...
