我在看论文时,看到如下式子,请高手帮忙指教如何得到回归结果的。万分感谢!!!

对库伊克模型做广义差分法,得模型:

对该模型做OLS估计,得:
Dependent Variable: DLY |
Method: Least Squares |
Date: 05/17/05
Time: 13:15 |
Sample(adjusted): 1985 2004 |
Included observations: 20 after adjusting endpoints |
Variable | Coefficient | Std. Error | t-Statistic | Prob.
|
C | 0.825406 | 0.182501 | 4.522756 | 0.0003 |
DLX | 0.109589 | 0.028922 | 3.789113 | 0.0015 |
DLY(-1) | 0.779055 | 0.052633 | 14.80168 | 0.0000 |
R-squared | 0.992375 |
Mean dependent var
| 5.196177 |
Adjusted R-squared | 0.991478 |
S.D. dependent var
| 0.419349 |
S.E. of regression | 0.038712 |
Akaike info criterion
| -3.527874 |
Sum squared resid | 0.025476 |
Schwarz criterion
| -3.378514 |
Log likelihood | 38.27874 |
F-statistic
| 1106.291 |
Durbin-Watson stat | 1.509597 |
Prob(F-statistic)
| 0.000000 |
回归结果显示,t检验值、F检验值及R2都显著。
修正过的模型为:lnYt=1.7098532+0.2270168lnXt+1.6138357lnYt-1
是怎么得到这个结果的,麻烦大虾帮忙呀!小弟不胜感激!!!
