In this paper, we describe and discuss some useful graphical approaches in regession analysis from two view points; one is to diagnosis certain structures underlying in fitted regression model and another is to check or evaluate sampling behaviors of the model, including check of outliers and influence observations and so on. Further, we introduce some recent graphical techniques based on computer graphic display. Most of the graphical methods are illustrated on two well-known examples, Hald's cement data and Brownlee's stack loss data.
