Textbook Question

Chapter 3.4, Problem 7C

Do these tools work for solving inequalities too? Let’s see. (Remember, by “work,” we mean that we can do these procedures to an inequality without changing whether it’s true or false.) We’ll use less than ( < ) to explore new rules, but the rules will also apply to greater than ( > ) , less than or equal to ( ≤ ) , and greater than or equal to ( ≥ ) . In Questions 1–4, fill in the comparison symbol that makes the inequality true after performing the operation.

Multiply both sides by 2.

Left side	Comparison symbol	Right side
10	<	20

Module Code: MATH380202 1. (a) Define the terms "strongly stationary" and "weakly stationary". Let {X} be a stochastic process defined for all t € Z. Assuming that {X+} is weakly stationary, define the autocorrelation function (acf) Pk, for lag k. What conditions must a process {X+) satisfy for it to be white noise? (b) Let N(0, 1) for t€ Z, with the {+} being mutually independent. Which of the following processes {X+} are weakly stationary for t> 0? Briefly justify your answers. i. Xt for all > 0. ii. Xo~N(0,) and X₁ = 2X+-1+ &t for t > 0. (c) Provide an expression for estimating the autocovariance function for a sample X1,..., X believed to be from a weakly stationary process. How is the autocor- relation function Pk then estimated, and a correlogram (or acf plot) constructed? (d) Consider the weakly stationary stochastic process ✗+ = + + +-1+ +-2 where {E} is a white noise process with variance 1. Compute the population autocorre- lation function Pk for all k = 0, 1, ....
