1. In combination in a system for detecting and predicting biological anomalies, comprising:
- (a) means for receiving electrophysiological signals;
(b) means for amplifying and digitizing said electrophysiological signals; and
(c) means for storing a data processing routine, said data processing routine for analyzing said digitized electrophysiological signals, said routine comprised of a set of application parameters associated with biological data correlating with biological anomalies, said routine capable of processing said digitized electrophysiological signals into signals detecting and predicting the onset of said biological anomalies, wherein said routine comprises;
space="preserve" listing-type="equation">PD2i˜
log C(n,r,nref*)/log r,where ˜
means scales as, C is the correlation integral for PD2i, in which n equals the data length, r equals the scaling range, and nref* equals a location of the reference vector for estimating the scaling region slope of log C/log r in a restricted small log-r range that is devoid of the effects of nonstationary data.
