You might look at the Stata command -vif-, but also the user written command -collin-, to understand more about your predictors as a set, and why each individually predicts Y, whereas as a set you have a significant model but lose significance on each individual coefficient. -Dave > Dear...

test x1=x2=xn=0 关键看三个地方,一个是判定系数R方,本图中,为0.9464,拟合优度很高。 第二看回归系数,本例中,常数项为9.347,系数为0.637, 第三看回归系数的显著性检验,即P值,本例中,x的系数的P值为0.000,小于0.05,说明x对因变量有显著的影响。其它的基本可以忽略。 扩展资料: Stata的统计功能很强,除...
2) How to perform a partial F test in STATA ? I think what you call a partial F test I call an incremental F test. Either that or I don't understand the question. Perhaps you want something like this: regress y x1 x2 x3 x4 ...
