The F-Test for Regression Analysis
The F-test, when used for regression analysis, lets you compare two competing regression models in their ability to “explain” the variance in the dependent variable.

The likelihood ratio test (LRT) “unifies” frequentist statistical tests. Brand-name tests like t-test, F-test, chi-squared-test, and so on are specific cases (or even approximations) of the LRT…
