Chapter 6, Problem 37SE

When the sample standard deviation S is based on a random sample from a normal population distribution, it can be shown that

E ( s )  =  2 / ( n  - 1 ) Γ( n /2) σ /Γ(( n  - 1)/2)

Use this to obtain an unbiased estimator for σ of the form cS. What is c when n = 20?

Consider an MA(6) model with θ1 = 0.5, θ2 = −25, θ3 = 0.125, θ4 = −0.0625, θ5 = 0.03125, and θ6 = −0.015625. Find a much simpler model that has nearly the same ψ-weights.
Let {Yt} be an AR(2) process of the special form Yt = φ2Yt − 2 + et. Use first principles to find the range of values of φ2 for which the process is stationary.
