Re: Knowing a unknowed time serie

Probably the best approach is to pose the question "can the dynamics of the time
series be described by a finite number of phase space variables ?".  An
excellent discussion of this is given in Tom Mullin's book "The Nature of Chaos"
ISBN 0 19 853990 8 Oxford University Press.  Chapter 7 "Distinguishing noise
from chaos" by Holton and May is particularly apposite and uses the above to
look at various examples, using the method of delay.  Easy enough to code into
Mathematica.
