3. Let {X} be an autoregressive process of order one, usually written as AR(1).
(a) Write down an equation defining X₁ in terms of an autoregression coefficient a
and a white noise process {} with variance σ².
Explain what the phrase "{} is a white noise process with variance o?" means.
(b) Derive expressions for the variance 70 and the autocorrelation function Pk, k
0,1,. of the {X} in terms of o2 and a.
Use these expressions to suggest an estimate of a in terms of the sample autocor-
relations {k}.
(c) Suppose that only every second value of X is observed, resulting in a time series
Y X2, t = 1, 2,....
Show that {Y} forms an AR(1) process. Find its autoregression coefficient, say
d', and the variance of the underlying white noise process, in terms of a and o².
(d) Given a time series data set X1, ..., X256 with sample mean = 9.23 and sample
autocorrelations ₁ = -0.6, 2 = 0.36, 3 = -0.22, p = 0.13, 5 = -0.08,
estimate the autoregression coefficients a and a' of {X} and {Y}.
#8 (a) Find the equation of the tangent line to y = √x+3 at x=6
(b) Find the differential dy at y = √x +3 and evaluate it for x=6 and dx = 0.3
Refer to page 96 for a problem involving the heat equation. Solve the PDE using the method of
separation of variables. Derive the solution step-by-step, including the boundary conditions.
Instructions: Stick to solving the heat equation. Show all intermediate steps, including separation
of variables, solving for eigenvalues, and constructing the solution. Irrelevant explanations are
not allowed.

Below is the code and output for an analysis of these data in R, with the sales data stored in the time series object X. Explain what is being done at points (i)-(iv) in the R code. Explain what is the difference between (v) and (vi) in the R code. Explain, giving reasons, which of (v) and (vi) is preferable. Write out the model with estimated parameters in full. (The relevant points in the R code are denoted #2#2#3#23 (i) #### etc.) Given that the sales for the four quarters of 2018 were 721, 935, 649, and 1071, use model-based forecasting to predict sales for the first quarter of 2019. (A point forecast is sufficient; you do not need to calculate a prediction interval.) Suggest one change to the fitted model which would improve the analysis.
