anova for objects inheriting
from class
glm.
See
anova for the general behavior of this function
and for the interpretation of
test.
anova.glm(object, ..., test)
When called with a single
glm object,
anova.glm may take a
while to run, because it fully iterates a series of
glm models.
The series is constructed by successively adding to the null
model all the terms in
object, taken in the order
they appear in
terms(object).
Some efficiency is achieved by computing the model matrix only once,
and using
glm.fit to perform the computations.
