This week I am posting another quiz, although no-one has yet solved the Spaghetti Graph Quiz. This one, suggested Demetris Koutsoyiannis may require some statistical analysis to solve. I have plotted the points up, and converted them to an R statement below.
The Quiz: The following numbers are synthetic, generated by a mathematical model. Can anybody decompose it into components such as trends, periodicities or whatever, and can one infer the type of the generating model?
