CH - 5 - Econometrics UG | PDF | Multicollinearity | Ordinary Least Squares The document discusses multicollinearity in econometrics, distinguishing between perfect and imperfect multicollinearity, their consequences on ordinary least squares (ols) estimators, and methods for detection and resolution. If the exact linear relation ship holds among more than two variables, we talk about multicollinearity; collinearity can refer either to the general situation of a linear dependence among the predictors, or, by contrast to multicollinearity, a linear relationship among just two of the predictors.

Econometrics Notes | PDF | Ordinary Least Squares | Multicollinearity The least squares produces wrong estimates of parameters in the presence of multicollinearity. this does not imply that the fitted model provides wrong predictions also. if the predictions are confined to x space with non harmful multicollinearity, then predictions are satisfactory.
