Team, Can some one help me in computing the R-squared value in glm. Thanks Aravindhan

Which version of a pseudo-R^2? What?s the model?

Hi David, I am using generalized linear models (glm command with family="poisson").

You still have not answered what sort of pseudo-R^2 measure you expected. http://www.econ.ucdavis.edu/faculty/cameron/research/jbes96preprint.pdf ? David.

... 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.
