Explanation Given information: [ 3 0 1 − 2 ] [ 1 0 − 1 2 4 1 ] Calculation: We have [ 3 1 0 − 2 ] [ 1 0 − 1 2 4 1 ] . The first matrix has dimensions 2 x 2 and the second matrix has dimension 2 x 3. Since the inner dimensions are equal, we can multiply the matrices. Moreover, the product should be 2 x 3-matrix. Multiply the rows of the first matrix with the columns of the second matrix (adding the products of the corresponding elements): [ 3 1 0 − 2 ] [ 1 0 − 1 2 4 1 ] = [ 3 ⋅ 1 + 0 ⋅ 0 1 ⋅ 1 + ( − 2 ) ⋅ 0 3 ⋅ ( − 1 ) + 0 ⋅ 2 1 ⋅ ( − 1 ) + < To determine (b) Find the product of [ 2 0 0 − 1 1 0 ] [ 1 5 − 2 3 − 4 2 ] . To determine (c) Find the product of [ − 1 2 ] [ 2 3 ] .

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.
