Question 3 (5101) Suppose that N ~ Poisson(A), and that X has a conditional distribution that depends on N. There are two possible models for this conditional distribution: . Model M: X|N=n~ N(2*n, o2 = 1) • Model M2: X|N=n~ N(2+n + n2,02 = 1) The only difference between M and M2 is the conditional mean function - the mean function is linear in M, and quadratic in M2. a If Mi is true: Find Ej[X] and V1 [X] as...
