T-test of linear regression
WebMay 20, 2024 Β· In simple linear regression, y = Ξ² 0 + Ξ² 1 X 1, the T-test for Ξ² 1 ^ is. H 0: Ξ² 1 = Ξ² 1 0 and H A: Ξ² 1 β Ξ² 1 0, where Ξ² 1 0 = 0, and the F-test is. H 0: Ξ² 1 = 0 and H A: Ξ² 1 β 0. We know that the T-statistics is. T = Ξ² ^ 1 s e ( Ξ² ^ 1) t n β 2. and F-statistics is.
