Dear dmfisher,

I guess that you talk about bear. Type I and Type III SS will be the same only when a 2x2x2 study is a balanced design. Otherwise, they are not the same. Doing this is just to mimic output results (Type I and Type III SS) obtained from SAS (PROC GLM). For more previous discussions of Type I and Type III SS with R, please search this Forum.

❝ [...] The column names are changed between these commands but the contents of the object are unchanged. This makes no sense — how could the values be the same for Type I and Type III SS?

All the best,
