[R-sig-eco] glm-model evaluation

[Manuel Spínola]

Dear list members,

I am fitting negative binomial models with the nb.glm function (MASS 
package).
I ran several models and did model selection using AIC.
How is a good way to evaluate how good is the selected model (lower AIC 
and considerable Akaike weight)?
Is model diagnostics a good approach?
Thank you very much in advance.

Best,

Manuel Spínola
