如何用stata做自相關存在性檢驗？

1、使用系統(tǒng)自帶的數(shù)據(jù)做RESET檢驗，sysuse auto，解釋：導入系統(tǒng)中自帶數(shù)據(jù)，autodescirbe解釋：看看數(shù)據(jù)的構成。

2、reg price rep78 headroom trunk weight length，解釋：對數(shù)據(jù)進行回歸。

3、使用y的擬合值進行RESET檢驗，estat ovtest，發(fā)現(xiàn)p的擬合值為0.051這個數(shù)比較接近拒絕域，我們認為我們可能遺漏了高次項。

4、直接使用解釋變量的高次項進行RESET檢驗，estat ovtest，rhs。解釋：添加了選項rhs，發(fā)現(xiàn)在5%的水平上拒絕原假設，認為遺漏了高階非線性項。

5、經(jīng)過數(shù)次嘗試之后，發(fā)現(xiàn)gen wight2=weight^2，reg price rep78 weight2 headroom trunk weight length，效果顯著。

2 Estat

estat給出了幾個非常有用的工具，包括KMO、SMC等指標。

Kaiser-Meyer-Olkin（KMO），是用于測量變量之間相關關系的強弱的重要指標，是通過比較兩個變量的相關系數(shù)與偏相關系數(shù)得到的。KMO介于0于1之間。KMO越高，表明變量的共性越強。如果偏相關系數(shù)相對于相關系數(shù)比較高，則KMO比較低，主成分分析不能起到很好的數(shù)據(jù)約化效果。根據(jù)Kaiser（1974），一般的判斷標準如下：0.00-0.49,不能接受（unacceptable）;0.50-0.59,非常差（miserable）；0.60-0.69，勉強接受（mediocre）；0.70-0.79,可以接受

（middling）；0.80-0.89，比較好（meritorious）；0.90-1.00,非常好（marvelous）。

SMC即一個變量與其他所有變量的復相關系數(shù)的平方，也就是復回歸方程的可決系數(shù)。SMC比較高表明變量的線性關系越強，共性越強，主成分分析就越合適。

根據(jù)KMO越高，表明變量的共性越強和SMC比較高表明變量的線性關系越強，共性越強，主成分分析就越合適。
