In the last post I described, how the features for the GS & PPG match rating models are calculated. Based on these features I will now describe, how you build and optimise a linear regression model with R. The first part will describe the optimisation of the linear regression model for the GS match rating model in detail. The second part will cover the PPG match rating model. The third and final part will compare the prediction performance of the different models.
Everyone, who follows my blog, will have noticed, that I did not published any post for a long time. This was because I first could publish my first article for the DOAG Business News and after that had two presentations at the DOAG conference.
