Depends on the `GLM' model and what you mean by that (general linear model, generalized linear model?). And by `Anova' (capitalized), for that matter.
S-PLUS (sic) does some inconsistent things with dispersion parameters in glm() fits, and it is likely that you are using the wrong test. But P values that near one should arouse your suspicions. Please read the R posting guide, and then tell us enough of what you did so we can help you. On Tue, 23 Mar 2004, Ridwan Sala wrote: > I tried to run a GLM model using S-Plus and R.
