Hi,
Is possible to anova function on R calculate the significance of complete glm
model?
I explain better.
I have a glm model:> model1 <- glm(nsp~caules+mo,family=poisson)
I make an anova of this:> anova(model1,test="F")
Analysis of Deviance Table
Model: poisson, link: log
Response: nsp
Terms added sequentially (first to last)
Df Deviance Resid. Df Resid. Dev F Pr(>F)
NULL 6 40.315
caules 1 23.436 5 16.879 23.4360 1.291e-06 ***
mo 1 0.545 4 16.333 0.5455 0.4601808
---
Signif. codes: 0 `***' 0.001 `**' 0.01 `*' 0.05 `.' 0.1 ` '
1
It OK, but I need to know the significance of model, I know how to calculate,
is not the problem, the question is: Exist a function that calculate this?
The deviance table that I need is:
Df Deviance Resid. Df Resid. Dev F Pr(>F)
NULL 6 40.315
caules 1 23.436 5 16.879 23.4360 1.291e-06 ***
mo 1 0.545 4 16.333 0.5455 0.4601808
Total 2 23.981 4 16.333 11.9905 0.000??? ***
This is my doubt. If the function anova dont make this, is possible to
implement this in function, or is a wrong idea?
Thanks for all :)
