c********8 发帖数: 5 | 1 我有一个线性回归的问题,请高手教我。
Model; Y=β0 + β1X1+ β2X2 + ε.
I want to test the hypothesis:
H0: β1 + β2= 1 vs Ha: β1 + β2 not equal to 1.
What test statistic I should use and what is its distribution? | d*********a 发帖数: 255 | 2 F-dist

| c********8 发帖数: 5 | 3 那和
test H0: β1=β2= 0 vs Ha: β1,β2 not equal to 0
有什么区别呢?F(df?,df?) | o******6 发帖数: 538 | 4 Ha should be "at least one coefficent is not equal to 0"
You can use wald test or likelihood ratio test;
