How many repeated measures factors do you have?  How many levels for each?  How many subjects?  

Have you seen this?

Dear all!

I have a problem with interpreting my withu+in subjects Anova results.
The sphericity table is not an expected one. I would be very grateful for your help!

Mauchly W is one, approx. chi square 0, df 0, SIgnificance - empty rows, Greenhouse-Geisser Epsilon 1.

Can I report the results using Greenhouse-Geisser Epsilon? It would be important, because the results are good!
Best regards,
