Created: 2010-05-28 16:31:01

Someone could help me? Why the correlation between the actual value and the predictive value of the attribute "Quantita" is so low?

    Hard to tell without the data. Anyway, I don't really understand the process. Why do you compute the correlation even before you compute the prediction?

    Because I would know if there is multicollinearity between the variables in the dataset
