Hi Andrew,

Thanks! There are two approaches "cell means approach" and 'factor effects approach' which are provided directly above and below the screenshot I provided, corresponding to the design matrix & contrast in my first and second post, respectively. In the screenshot, it is said that these two approaches are equivalent. If I understand correctly, you mean that NBS only supports the approach below the screenshot (i.e., in my second post), while the "cell means approach" directly above the screenshot (i.e., in my first post) is not supported in NBS?

Thanks and sorry for my continuing question.

Regards,

Jeff
