Dear Guillaume,
Thanks so much for your prompt reply. I clicked the subscribe link, filled out some info and is still waiting for the subscription confirmation letter.
I've also tried what you've suggested. However, I still have one question regarding to this One way ANOVA model. Because Factor 1 is obtained during MC phase of Control subjects, and Factor 2 is obtained during OV phase of the same Control subjects. So they sure are not independent. And Factor 3 and Factor 4 (Patients_MC phase, patients_OV phase, respectively) are not independent either. However, Factor 1 and factor 3, or Factor 2 and factor 4 should be independent to each other. Does this model representative enough to this problem?
Additionally, looking back to the 2-by-6 model I originally specified. If I contrast them with t-test: [0 0 0 0 1 -1] or [0 0 0 0 -1 1] what are we really testing?
Hope I will be able to send my question to the mailing list soon!
Thank you so much.
Best,
Naomi
