Year of publication:
The polarity coincidence correlator (PCC) is a useful nonparametric measure of correlation. In this paper, an error is pointed out in the significance test given by Cochran and Gibson (1977). Some further theoretical and practical issues are mentioned pertaining to the use of PCC with physiological waveforms; in particular, problems relating to autocorrelation and the definition of the sampling unit are discussed.
