teau, it “saturates”. This is but one of a range of geometric scaling exponents, “dimensions,” that are currently being computed (Farmer et al, 1983; Grassberger and Procaccia, 1983; Meyer-Kress, 1986; Theiler, J. (1990); Gershenfeld, 1992; Ott et al,, 1994). Although still subject to debate, convention has it

tudies that invoke scaling exponents to quantify the distributions of points on the attractor as reconstructed from time series in the neurosciences (Grassberger and Procaccia, 1983; Mayer- Kress, 1986; Ott et al, 1994). Several sets of programs are available for its computation (for example, Sprott and Rowlan
