Recurrence plots were introduced to aid in the detection of signals in complicated data series. This effort was taken a step further by the quantification of recurrence plot elements. We now demonstrate the utility of combining recurrence quantification analysis with principal components analysis to allow for a probabilistic evaluation of the presence of deterministic signals in relatively short data lengths. © 1998 Elsevier Science B.V.
