deviance

Does anyone know the answer to this question? I am assuming it is not model 1 since it has the highest residual deviance ..

Hi! This might be quite basic, but how do I analyse the fit of my GLM from the deviance? In the summary of my model, I get a deviance of 140.1 (df.resid = 52). Can I tell from these numbers, if the fit is acceptable? Thanks in advance for any replies!:tup:

Hello, I’m working with a poisson model to look at relationships between fish and habitat. I have multiple-pass count data (the same pool snorkeled multiple times), and I’m using a program called “unmarked”, which uses hierarchical models to estimate both abundance (poisson) and detection...

Hello, I am trying to fit a log linear model with proc genmod and when i include all interactions (3 variables) i get the following: Criterion DF Value Value/DF Deviance 0 0.0000 . Scaled Deviance 0...

can anybody please tell me why we need to multiply difference of likelyhoods by "-2"? Where this 2 came from, why not 3? Could not find answer
