A visual procedure for optimal response transformations and curvature specifications
- 67 Downloads
Consider a general regression model in which a covariate enters nonlinearly with a power transformed response variable. Under this formulation a dynamic graphical procedure using inverse response plot and forward response plot is suggested for finding an optimal response transformation parameter value and capturing a curvature. Examples demonstrate that the method works well and also can be used to detect the influential cases.
