2. (10 points) Let XP, and let ^ denote the MLE of . Suppose that h is a one-to-one function
from onto h(). Define =h() and let f(x,) denote the density or frequency function of X in terms of
(i.e., reparametrize the model using ). Show that the MLE of is h(^) (i.e., MLEs are unaffected
by reparametrization, they are equivariant under one-to-one transformations).
