WebThe ANOVA analysis performs an F test that is similar to the F test for a linear regression. The difference is that this test is between two models, whereas the regression F test is between using the regression model and using no model. WebANOVA and OLS regression are mathematically identical in cases where your predictors are categorical (in terms of the inferences you are drawing from the test statistic). …
