When is Piece-Wise Regression Really Necessary? |
|
| Authors: | I B Onukogu |
| Abstract: | Results are obtained showing that when a response surface can be modelled as a single function, then a single regressor is more efficient and less biased than a segmented regression. However, if the surface is segmented, a segmented regressor is less biased than a single regressor. Areas of application are indicated. |
