External Email - Use Caution Hi all,
I am doing an analysis and generating the FSGD. I understand sex and race are classes in this context, but something I was also hoping to regress out is the effects of scanner/sequences. We have a large participant size, so we have around 10+ scanner/sequences, which makes for a large amount of classes combinations, with some having just 1 (if not zero) fitting into a class. Would you proceed with this nonetheless? If not, should scanner/sequence be something that we consider? Should we find some other way to adjust site (I don't think we can z-score...). Or can we consider site/scanner as a continuous variable Victor Zeng Beth Israel Deaconess Medical Center Keshavan Lab --
