Hi everyone,
I would like to know if there is a possibility to estimate how well the model created by 3ddeconvolve fits the bold response, overall for a participant. I know how to do this manually, by plotting the fitted model against the bold for each individual voxel, but I would like to have a number that summarizes the fit for the whole brain. If I am not wrong, the "full_Fstat" that 3ddeconvolve creates measures the goodness of fit, but again, this is computed for every voxel. I wonder if I could average these F-values across the whole brain. Would that make statistical sense? Would it not be better to average the R squares?
Thank you!
Guillaume
