First of all, I have to thank you for the amazing content you have provided us on udemy. I’ve been enjoying it thoroughly and because of it, I currently have a paper in the publishing process.
My question regards the baseline normalization of the time-frequency plots on my current research project. I’m doing a time-frequency analysis comparing a group of people with the diagnosis of schizophrenia (SZ) to a group of healthy controls (HC) where each participant was subjected to 3 experimental conditions.
Now, I understand the motivation for averaging the baseline of all 3 conditions, but should I do it for every different individual and then average all the resulting baselines for each group (SZ vs. HC) separately? Should I even have a different baseline for each group?
