Assignment 4: Due Tuesday February 7

Reading:

van der Vaart, Asymptotic Statistics: Section 2.1 and 2.2, 3.1 and 3.2

Ferguson Sections 5-9

Problems:

Ferguson 1.1 (first part only), 1.2, 1.3, 1.4, 2.6, 3.1(a,b,d), 5.1, 5.7 (use the Lindebergh CLT)

Ferguson Problem 4.1. First carefully evaluate the expected value of beta-hat and alpha-hat. It follows from this that the relevant quantity to consider in parts a,b of the question is the variance of the the estimates. Recall that converence in quadratic mean (qm) is equivalent to L_2 convergence.
