(a)
Discuss whether the given data is a univariate time series or not (max. 200 words).
(10 marks)
(b)
If the researcher wanted to study the general yearly development of the crime rate
(occurrence of crime cases) in the United States between 1994 and 2014 and forecast
future criminal rate based on the given dataset, what would be your suggestion on how
to reshape this dataset to meet his study requirements? Write down your data
preparation plan step by step in point form without going into detail or including any
screenshots (max. 300 words).
Note: It is not an Excel exercise. Therefore, you should not describe the steps you would
conduct in Excel for this task. Instead, you must describe how you can construct such
a time series in general data preparation terms.
(20 marks)
(c)
The researcher has then decided to use the time series of the nationwide (entire USA)
monthly average victim age for his study, regardless the type of crime that was
committed. Prepare the data accordingly and report your steps in point form with all
necessary screenshots (max 400 words, each screenshot should not have a height of
more than 7cm).
(40 marks)
(d)
Construct useful charts and calculate relevant statistics in SAS for the time series.
Explain in less than 200 words (excluding the SAS code) why these charts or statistics
are significant in analysing and forecasting future values of the time series (each
screenshot should not have a height of more than 7cm).
(20 marks)
(e)
From the statistics and charts created in part (d), evaluate how the average age of the
victims had been developing between 1994 and 2014. Present your argument in less
than 200 words.
