Hello List,
We are working a project to explore the changes in OCD and their siblings. There are total 69 subjects of 28 controls, 26 patients and 15 siblings of patients. I did comparing each pair of the three groups as design_subs69.png.
Currently, I want a unified ANCOVA design as design_subs69_ancova.png.
My question is what is the difference in statistical power and outcomes given by FEAT commands?
I know there would be some questions on setting models for this sample regarding the ocd-sibs closeness than that of ocd-con in generation, do you have more suitable approaches for addressing this issue? Or what is the common way of dealing with patients-sibs-controls data mining in this field?
Any of your inputs are greatly appreciated!
Best Regards,
Xi-Nian Zuo
