✦ Synopsis

We assume a multiple regression model in which the relation between a response variable and one of independent variables is nonlinear. CERES plot, an acronym for "Combining Conditional Expectations and RESiduals" is proposed by Cook (1993, Technometrics, 35, 351-362) for uncovering the function of nonlinearity. A dynamic display of CERES plots is suggested to understand the e ect of adding variables to the model on the form of the nonlinearity.
