統(tǒng)計和優(yōu)化實驗論文

1、論文一本論文根據(jù)2000年到2013的房價進行正態(tài)白噪聲檢驗、異方差檢驗、序列相關(guān)性檢驗、多重共線性檢驗、參數(shù)的T檢驗、方程的F檢驗。城鎮(zhèn)居民人均總收入(元)aty城鎮(zhèn)居民人均工資性收入(元)agy城鎮(zhèn)居民人均經(jīng)營凈收入(元)ajy城鎮(zhèn)居民人均財產(chǎn)性收入(元)acy城鎮(zhèn)居民人均轉(zhuǎn)移性收入(元)azy城鎮(zhèn)居民人均可支配收入(元)aky城鎮(zhèn)居民家庭人均現(xiàn)金消費支出(元)axc6,295.904,480.50246.2128.41,440.806,280.001,971.306,907.104,829.90274.1134.61,668.606,859.602,014.008,177.405,740

4、97,010.3026,955.1018,022.60用Eviews做一次線性回歸得：初步得：aty=acy+agy+ajy+azy1、 正態(tài)白噪聲檢驗用Eviews軟件求得：其JB值=4.9842.354,則存在一階自相關(guān)。4、 多重共線性檢驗F=2.5*10(10)F0.05(6,14)=2.24,表明aty與各解釋變量間線性關(guān)系顯著。由Eviews做表得：由上表的，解釋變量間存在高度的線性相關(guān)性。5、 參數(shù)的T檢驗由上得：常數(shù)回歸值為0.18，p值為0.680.05,則常數(shù)與0沒有顯著性差異，即不應(yīng)存在；azy回歸值為1，p值為00.05,則azy與0有顯著性差異，即應(yīng)存在；acy回歸值為1，p值為00.05,則acy與0有顯著性差異，即應(yīng)存在；agy回歸值為1，p值為00.05,則agy與0有顯著性差異，即應(yīng)存在；ajy回歸值為1，p值為00.05,則aky與0沒有顯著性差異，即不應(yīng)存在；axc回歸值為7.2*10(-6)，p值為0.630.05,則axc與0沒
