Sir, I was going through the question Sauce Co. from June 2012, and I noticed that they have asked on the calculation of multiplicative model, so I just want to know that since this is F2 topic can they ask this type of question in exam? or this was included in previous syllabus and this has changed now?
The examiner has stated that you can no longer be asked calculations on time series analysis (and the same applies to regression analysis). You are expected to have heard of the idea (because they are assumed knowledge from F2) but there will be no calculations. (This is clearly stated in our free lecture notes, in the introduction to Chapter 12)).
