Web15 aug. 2024 · The F-test statistic is based on a ratio that asks how much worse the restricted model fits relative to the unrestricted regression. In other words, we ask: how much larger is SSR_r compared to SSR_u as a percentage expressed in decimal terms? (SSR_r - SSR_u) / SSR_u ## [1] 0 .4116171 There is nothing subtle going on here. Web16 jul. 2024 · The most common threshold is p < 0.05; that is, when you would expect to find a test statistic as extreme as the one calculated by your test only 5% of the time.
