Cоnsider 4 pоssible predictоr vаriаbles to be included in а regression model. The following table reports the coefficients of determination when each predictor is regressed on the remaining independent variables in turn. (For example, the value of the coefficient of determination when X1 is regressed on X2, X3 and X4 is 0.41). Is there any reason to believe there may be a multicollinearity problem? If so, which predictor/s ought to be excluded from the model when the rest are included? [Hint: consider a measure of multicollinearity.] Predictor variable X1 X2 X3 X4 Coefficient of determination for Xi on other X's 0.41 0.27 0.72 0.39
