Compute odds ratio in r using glm

Webbase package in R. The negative binomial is t using the glm.nb function in MASS. Finally, the beta regression is t via the betareg package. Both betamfx and betaor functions use a logit link for the mean function, so it is feasible to calculate both marginal e ects and odds ratios for these models. 4.
