[Eeglablist] Residual Variance

[Thornton, David M]

EEGLAB Community,

Does anyone know of any correlations between epoch length and dipole residual variance? My most recent study has been plagued by higher residual variances (most >20%) than previous studies using similar stimuli and response procedures. The only difference is the epoch length, which has increased from 5 to 6 seconds. I'm skeptical that this would cause some issues with residual variance, but I'm running out of ideas to try and figure out what is at the root of the problem.

Thanks everyone,
David Thornton
