| English abstract: |
| This paper was to introduce the application of the building regression model adopted the adaptive regression spline algorithm on the data sets with mixed structure through two examples. When a data set contained several distinct regression models, the ADAPTIVEREG procedure in SAS software could discover the internal rules as long as the specific values of the classification variables were given, and could present the fitted results of the model with graphs and the regression model constructed with the basis functions and their combinations. The information presented in the graphs could provide some valuable analytical clues or positive hints for the analysts, which greatly reduced the space of the exploratory research. |
