I am in need of the type III ANOVA à la SAS for GLM and MixedModels (with support for rank deficient). A similar tool is the car::Anova(::lmerMod, type = 3) function in R. I am not an expert in ANOVA since I tend to use the standard Wald test routine, but for some software I am developing it is standard to report that ANOVA test. I am willing to implement these given some guidance on the procedure. I can start with a PR to handle the rank deficient LinearModel. Given some guidance, I can also extend the functionality to the LinearMixedModel.
