Multiple Hypothesis Testing: The F-test - Matt Blackwell

WebMar 26, 2024 · F-statistic: 5.090515. P-value: 0.0332. Technical note: The F-statistic is calculated as MS regression divided by MS residual. In this case MS regression / MS residual =273.2665 / 53.68151 = 5.090515. Since the p-value is less than the significance level, we can conclude that our regression model fits the data better than the intercept … WebThe f test is a statistical test that is conducted on an F distribution in order to check the equality of variances of two populations.
