WebMay 9, 2016 · Let β ^ be your regression estimates of β. Under the condition that β ^ ∼ N ( β, Σ) conditional on data X (eg. β ^ asymptotically normal with mean β and covariance matrix Σ) then the linear restrictions R β = r can be tested with a χ 2 test. Observe that R β ^ − r would be normal with V a r ( R β ^ − r ∣ X) = R Σ R ′. WebJul 18, 2015 · R 2 = 1 − ( 1 + F ⋅ p − 1 n − p) − 1. where F is the F statistic from above. This is the theoretical relationship between the F statistic (or the F test) and R 2. The practical interpretation is that a bigger R 2 lead to high values of F, so if R 2 is big (which means that a linear model fits the data well), then the corresponding F ...
