Dear all, I'm performing poisson regressions using the glm(family=poisson) and zero-inflated regressions using the zeroinfl from the package pscl. However any of those give an R^2 and I was wondering if there is a way to get it.
R^2 is meaningless for such models. They are fitted via maximum
likelihood, not least squares.
cheers,
