When quasi family (not quasipoisson or quasibinomial) is used in glm, what is the appropriate test statistic in anova.glm? Help of anova.glm tells ?For models with known dispersion (e.g., binomial and Poisson fits) the chi-squared test is most appropriate, and for those with dispersion estimated by moments (e.g., gaussian, quasibinomial and quasipoisson fits) the F test is most appropriate?. I assume that F is appropriate in the case of quasi (not quasipoisson or quasibinomial). Is this correct? Ei Kasuya

Yes. References are Venables and Ripley (i.e. MASS) and Crawley's Statistical Data Analysis book. Ben Bolker
