Anova Tables

Compute analysis of variance (or deviance) tables for one or more fitted model objects.

Keywords
models, regression
Usage
anova(object, …)
Arguments
object

an object containing the results returned by a model fitting function (e.g., lm or glm).

additional objects of the same type.

Value

This (generic) function returns an object of class anova. These objects represent analysis-of-variance and analysis-of-deviance tables. When given a single argument it produces a table which tests whether the model terms are significant.

When given a sequence of objects, anova tests the models against one another in the order specified.

The print method for anova objects prints tables in a ‘pretty’ form.

Warning

The comparison between two or more models will only be valid if they are fitted to the same dataset. This may be a problem if there are missing values and R's default of na.action = na.omit is used.
