    Collinearity of variables and linear regression

    Ok, i'll try to explain it better: I created one data frame with two explicatives variables with multicollinearity between them: Here is the result of the analyse of variance of the multiple regression model made with firt Y~X1+X2 and second Y~X2+X1 Here are the results: AS you can see, de SSQ...
