Webpredicted values (Montgomery, 2001). Because multicollinearity is a serious problem when we are working for predictive models. So it is very important for us to find a better method to deal with multicollinearity. A number of different techniques for solving the multicollinearity problem have been developed. WebImplications of regressing Y = f (x1, x2) where Y = x1 + x2 + x3. In various papers I seen regressions of the sort of Y = f (x1, x2), where f () is usually a simple OLS and, importantly, Y = x1 + x2 + x3. In other words, regressors are exactly a part of Y. portal fighting game
