Forecasts of football scores

Hi all,
i'm new in this forum.
I am studying different models to predicting results of football matches. In my opinion it would be very useful to use time series to improve the predictive accuracy of this problem.
I would like to use functionality windowing in rapidminer such as in the financial forecasts (http://www.neuralmarkettrends.com/2010/03/30/rapidminer-5-0-video-tutorial-9-financial-time- series-modeling-part-1 /).
There is a problem: the variable to predict is a nominal variable [1, X, 2].
I have converted this variable in numeric by using the "nominal to numeric". Obviously the result of predicted variable is a real number between [-1932, 3637]. How should I interpret these results? is the correct approach to the problem or I can not deal with nominal variables in the time series in rapidminer?
Thank you very much
Best regards

    Hi,

    you should NOT convert your label to numerical if it's really nominal! That changes from a classification task to a regression task, making the same much more difficult. You can do windowing with nominal attributes...

    PS: Won't work. We already tried to forecast football results :)
