Abstract

A new improving method to compute Spearman rank correlation test has been developed. This method is based on the use of a response to stimulation delay referred by many authors. Visual results tend to prove the method efficiency which is confirmed by obtained overlap rates; moreover this method can easily be adapted in a clinical context.
