Quarterly sales of videos in the Leeds "Disney" store are shown in figure 1. 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. (You
can assume that the choice of stochastic process at (v) in the R code is the correct
one for these data.)
