The Bagplot is a bivariate generalization of the univariate boxplot which is also used in determining the outliers. Hence it can be used in diagnosing the outliers for the simple linear regression. It cannot be used, however, when the number of variables exceeds one. On the other hand, in statistics literature, it has been shown that the predicted value versus residual plot can represent the whole data in some instances. The main motivation of this paper is that point. The performance of the Bagplot in the predicted value versus residual plot is investigated for some classical and simulated data sets. The approach is found successful for many scenarios.
