Hi guys.

Can anybody give me a hint on how the feature weightings of Chi squared and information gain are calculated and how they are normalized?

I have already figured out how the normalized version of chi squared is calculated, now I just need the normalization technique as well. Information gain I have not been able to reproduce based on the formulas I have available through literature.
