You have monthly sales data on surfboards ranging from January 2017 to September 2018

The training set will now be all of 2017. Will need to create sequence of 9 forecasts for January 2018 to September 2018 using the mean, naive, seasonal naive and drift methods.

Create one page with your name, student number and date on it. On page 2 create table, using LaTeX, containing: the data for 2018, your mean, naive, seasonal naive and drift forecasts (total of 6 columns including the time index column). Page 3 (and maybe a page 4) should show your calculations (9 forecasts x 4 methods = 36 calculations). Make sure that you use the correct indices specially for the seasonal naive equations. Use the math environment in LaTeX to create all of your equations. Create also an Appendix containing your LaTeX script used to generate your pdf.

Data is attached below.
