请高手支招啊!
我用STEPLS做了多重共线性的自动逐步回归,如果如下:
Dependent Variable: Y |
|
| ||
Method: Stepwise Regression |
|
| ||
Date: 08/10/14 Time: 09:34 |
|
| ||
Sample: 1996 2012 |
|
| ||
Included observations: 17 |
|
| ||
Number of always included regressors: 9 |
| |||
No search regressors |
|
| ||
Selection method: Stepwise forwards |
| |||
Stopping criterion: p-value forwards/backwards = 0.5/0.5 | ||||

我的问题是:应该如何判断回归的结果呢?No regressors were chosen by the stepwise routine(没有回归的逐步程序选择)是怎样理解的呢?
