Then βˆ GLS is the BUE for βo. Under the null hypothesisRβo = r, it is readily seen from Theorem 4.2 that (RβˆGLS −r) [R(X Σ−1o X) −1R]−1(Rβˆ GLS −r) ∼ χ2(q). The left-hand side above can serve as a test statistic for … Web我们依然可以使用 ols 进行线性回归。但前提条件是，我们必须知道 x 在这个关系中的所有次方数；比如，如果这个公式里有一个 x^{2} .5项，但我们对此并不知道，那么用线性回归的方法就不能得到准确的拟合。. 虽然 x 和 y 的关系不是线性的，但是 y 和 x,x^{2} ,...x^{n} 的关系是高元线性的。 snapchat easter egg hunt
