1 = .*.vk-1e-ta 1. Suppose that X is a random variable with a Gamma-(k, 1) distribution where k > 0 is known, but > 0 is unknown Væ € (0,1), we have f(x) T(k) Let us use 0 = 1/ which is the standard approach, for example in Hogg and Tanis. Calculate the Fisher information I(C). 2. Continuing with problem 1, suppose that X1, ..., Xn are IID copies of the random variable X. Suppose we...
