   8 sie 2022 · We use aov() when we would like to fit an ANOVA model and view the results in an ANOVA summary table. We use anova() when we would like to compare the fit of nested regression models to determine if a regression model with a certain set of coefficients offers a significantly better fit than a model with only a subset of the coefficients.
