Dear Freesurfer experts,
I know this has been an ongoing topic in the mailing list – however I would like to raise the issue one more time. In the choice between doss and dods – I usually check if there is a significant interaction and if so my choice is dods.
As I understand it you do not recommend to use doss if an interaction is present. Is the reason for this that I would “over-correct” for the variable in one group while “under-correcting” for the same variable in the other group?
It is some time tempting to present result both from a dods and a doss – to tell where the interaction is present, and where difference are present while controlling for the variable
But if I understand Doug´s previous comments on this – this would not be a correct approach?
Thanks
Erik
