... and I would further add to David's comments that R^2 is basically
nonsense for glm's (and mostly for lm's also -- but not a topic for
further discussion here). Likelihood ratio tests are what should be
used to judge model fits for glm's -- also not a topic for further
discussion here. Consult a local statistician, do your glm homework,
or post on stats.stackexchange.com for statistical follow-ups.
