anova {stats} | R Documentation |
Compute analysis of variance (or deviance) tables for one or more fitted model objects.
anova(object, ...)
object |
an object containing the results returned by a model
fitting function (e.g., |
... |
additional objects of the same type. |
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.
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.
