Dear yjlee,

❝ O.k., does this sequential phenomenon occur with SAS for type I SS calculation? The suggested SAS codes for 2x2x2 crossover is

(...)

❝ Looks like that we need to put seq before subj...

Yes to the first question. Type I is defined that way, so you will see the same phenomenon with SAS type I (unless SAS is does something clever as it does for the single term deletion stuff; this I don't know about as I do not use SAS).

The SAS default I think includes type I and type III in the output. You can put Seq before Subj in type I analyses if you prefer. As explained previously that will ensure you get 'something' for the Seq SS.
