Abstract
Principal component analysis of event‐related potentials is known to be suspect when underlying components have varying latency. In this note it is theoretically shown that approximately an additional component may be assumed, being the time‐derivative of the underlying component. Validity of this approximation is demonstrated in a simulation study.Keywords
