Improved Waveform Estimation Procedures for Event-Related Potentials

Several methods of estimating the waveform of event-related potentials are presented. The techniques of conventional averaging, Woody cross-correlation averaging, latency corrected averaging, continuous latency corrected averaging, and enhanced averaging are described and their results compared. It was found that the continuous latency corrected average appears to offer the most useful representation of the waveform of the event-related potential.
