We will look at the Olympics from 1964 through to 2008. For each year, we will run a predictive model, trying to predict the number of medals a country wins, using selected datasets that are available before each of the Olympics. We will see that this model performs well out of sample and this model will be what we expect. http://www.batisengul.co.uk/post/analysis-of-calving-of-jh-dorrington-farm-part-iii/ Tue, 10 Oct 2017 00:00:00 +0000 batisengul@gmail.com http://www.batisengul.co.uk/post/analysis-of-calving-of-jh-dorrington-farm-part-iii/ Drum roll please. This is the long awaited third and final part of the analysis from JH Dorrington Farm. If you have not already, read the first part and second part. Leaving where I left off, almost all of our models fit pretty well except for CART, so in what follows, I will ignore the CART model. That leaves us with linear regression models and MARS. MARS essentially builds a piecewise linear model using hinges.
