I’m just looking at this question and I can’t see this in my 2012 Kaplan book which is a bit worrying. I do have the regression formula e.g Y=150+10X could you please firstly show me how they have calculated the moving averages and secondly show me how I would arrive at the same answer using linear regression
The examiner has said that she will no longer ask regression or time series calculations – that is why it is not in your Kaplan book. (And she has removed the regression formulae from the formula sheet)
