Consider the probability space (W, A , P ), and let Q be an open subset of
Question:
Now let p(x; q) = ½ e |x q|, x à à (q à Ã) to be double exponential probability density function, and for q, q* à Ã, Set
(i) Show that g(x; q, q*) is not ponitwise differentiable with respect to q* at (q, q) for any q = x à Ã.
(ii) If the r.v. x is distributed according to p(Ã; q), show that g(X; q, q*) is differentiable in qm. With respect to q* at (q, q) Ã Ã, with q.m. derivative g(X;q) given by:
