Two residual plots in the first row (purple box) show the raw residuals and the (externally) studentized residuals for the observations. The first graph is a plot of the raw residuals versus the predicted values. Ideally, the graph should not show any pattern. WebPrepare a normal probability plot of the residuals. Also obtain the coefficient of correlation between the ordered residuals and their expected values under normality. Test the reasonableness of the normality assumption here using Table B.6 and a = .05.
