WebMar 31, 2024 · F = RSS 1 − RSS 2 RSS 2 / ( n − k − 1) ∼ F ( 1, n − k − 1) This is from Jack Johnston & John DiNardo's "Econometric methods". In a later example, they use this F-test to test for differential intercepts. However, the critical value they take at the 5% significance level is the critical value for a single tailed test! WebStep 3: F-Test Formula: F Value = Variance of 1st Data Set / Variance of 2nd Data Set. Step 4: Find the F critical value from F table taking a degree of freedom and level of significance. Step 5: Compare these two values and if a critical value is smaller than the F value, you can reject the null hypothesis.
