However, in the simple linear regression case, it is not necessary to plot residualsversus both fitted value and the regressor variable. The reason is that the fitted values are linearcombinations of the regressor values, so the plots would only differ in the scale for the abscissa.1.3)The ridge estimator of the regression coefficients in a multiple linear regression model is a nonlinear transformation of the least-square estimator.1.4)For a qualitative variable with m levels involved in a multiple linear regression, one can representit by m- 1 indicator variables.
