Sum-of-Squares Types in *Lm functions #256

Open gdevenyi opened 5 years ago

gdevenyi commented 5 years ago

We were recently discussing some more intricacies of linear models and came across the discussions of the lm sum of squares default.

So, the question arises, what are the sum-of-squares choices for the *lm functions in RMINC, since some of the code underneath the models is custom.

Thanks for the clarifications :)

I assume you mean for ANOVA type analyses?

gdevenyi commented 5 years ago

Right, so after more reading. I see what I missed, this type of question applies to the anova run on an lm, which isn't the kind of thing we do here.

But yes, it would be helpful to know which sum of squares type is used for the anova functions.
