The title says it all. Based on historic games, and a complete set of variables, I would like to create a model, in which I can tweak the weight of each variable to come to statistical forecasts and predictions. It's a little difficult to explain here, but the key is to be able to data scrape the history from the internet, and be able to apply all variables to an "econometric model". I don't think it should take more than a few hours of work, if you qualify for the task.
