Linear Regression of Italian bookshops sellout data
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
I have uploaded datasource file of Italian bookshops sellout used in the process.
Where have you uploaded it? Is it available for public?
