一、
多元線 性回歸模型的建立
Dependent Variable: Y
Method: Least Squares Date: 06/22/10
Time: 20:30 Sample: 1978 1994 Included observations: 17 Variable Coefficient Std. Error t-Statistic Prob.
C -675.3208 2682.060 -0.251792 0.8051 T 77.67893 115.6731 0.671538 0.5136 L 0.666665 0.853626 0.780980 0.4488 K 0.776417 0.104459 7.432745 0.0000 R-squared 0.995764
Mean dependent var 6407.249 Adjusted R-squared 0.994786
S.D. dependent var 2486.742 S.E. of regression 179.5630
Akaike info criterion 13.42125 Sum squared resid 419157.5
Schwarz criterion 13.61730 Log likelihood -110.0807
F-statistic 1018.551 Durbin-Watson stat 1.510903
Prob(F-statistic) 0.000000
因此,我國國有獨立工業(yè)企業(yè)的生產(chǎn)函數(shù)為:
K L t y 7764 . 0 6667 . 0 6789 . 77 32 . 675 ˆ ? ? ? ? ?
(模型 1)
t =(-0.252) (0.672)
(0.781)
(7.433) 9958 . 02? R
9948 . 02? R
551 . 1018 ? F
9958 . 02? R ,說明模型有很高的擬合優(yōu)度,F(xiàn) 檢驗也是高度顯著的,說明職工人數(shù) L、資金 K 和時間變量 t 對工業(yè)總產(chǎn)值的總影響是顯著的。但是,模型中其他變量(包括常數(shù)項)的 t 統(tǒng)計量值都較小,未通過檢驗。因此需要做適當(dāng)?shù)恼{(diào)整。
二、建立剔除時間變量的二元線性回歸模型 Dependent Variable: Y Method: Least Squares Date: 06/22/10
Time: 20:36 Sample: 1978 1994 Included observations: 17 Variable Coefficient Std. Error t-Statistic Prob.
C -2387.269 816.8895 -2.922390 0.0111 L 1.208532 0.273020 4.426528 0.0006 K 0.834496 0.057421 14.53287 0.0000 R-squared 0.995617
Mean dependent var 6407.249 Adjusted R-squared 0.994990
S.D. dependent var 2486.742 S.E. of regression 176.0069
Akaike info criterion 13.33771 Sum squared resid 433697.8
Schwarz criterion 13.48475 Log likelihood -110.3705
F-statistic 1589.953 Durbin-Watson stat 1.481994
Prob(F-statistic) 0.000000
此時我國國有獨立工業(yè)企業(yè)的生產(chǎn)函數(shù)為:
K L y 8345 . 0 2085 . 1 27 . 2387 ˆ ? ? ? ?
(模型 2)
t =(-2.922)
(4.427) (14.533) 9956 . 02? R
9950 . 02? R
953 . 1589 ? F
模型 2 的擬合優(yōu)度較模型 1 并無多大變化,F(xiàn) 檢驗也是高度顯著的。但這里,解釋變量、常數(shù)項的 t 檢驗值都比較大,顯著性概率都小于 0.05,因此模型 2 較模型 1 更為合理。
三、建立非線性回歸模型 ——C C- -D D 生產(chǎn)函數(shù)
Dependent Variable: LNY Method: Least Squares Date: 06/22/10
Time: 20:42 Sample: 1978 1994 Included observations: 17 Variable Coefficient Std. Error t-Statistic Prob.
C -1.951253 1.665320 -1.171698 0.2609 LNL 0.604467 0.272697 2.216625 0.0437 LNK 0.673658 0.072357 9.310131 0.0000 R-squared 0.995753
Mean dependent var 8.692837 Adjusted R-squared 0.995147
S.D. dependent var 0.394921 S.E. of regression 0.027512
Akaike info criterion -4.189602 Sum squared resid 0.010597
Schwarz criterion -4.042564 Log likelihood 38.61162
F-statistic 1641.407 Durbin-Watson stat 1.338201
Prob(F-statistic) 0.000000
C-D 生產(chǎn)函數(shù)的估計式為:
K L y ln 6737 . 0 ln 6045 . 0 9513 . 1 ˆ ln ? ? ? ?
。P 3)
t =
(-1.172)
(2.217)
(9.310) 9958 . 02? R
9951 . 02? R
407 . 1641 ? F
從模型 3 中看出,資本與勞動的產(chǎn)出彈性都是在 0 到 1 之間,模型的經(jīng)濟(jì)意義合理,而且擬合優(yōu)度較模型 2 還略有提高,解釋變量都通過了顯著性檢驗。
實驗四
異方差模擬實驗
一、實驗?zāi)康模毫私猱惙讲钅P偷臋z驗方法和異方差模型的處理方法。
二、實驗要求:
