Effect size & MANOVA

[Tom Gumpel]

Hello all,
New to STATA.
I am trying to calculate eta2 or partial eta2 for a MANOVA:

manova relational physical = grade gender grade#gender

Suggestions?

As a follow-up and clarification, I am looking to calculate the eta2 for Wilks Lambda.
Using "return list", the scalars presented (df, F) are for Roy's Largest root and so I can't create a formula.
