   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.

   25 lis 2016 · aov fits a model (as you are already aware, internally it calls lm), so it produces regression coefficients, fitted values, residuals, etc; It produces an object of primary class "aov" but also a secondary class "lm". So, it is an augmentation of an "lm" object.
