  There are caveats to this line of thinking, however. First, the prefractal character of the analyzed data sets (e.g. by Avnir, et al. 1998) could be an artifact of the way data is massaged before it is analyzed or due to the analog-to-digital conversion that must take place before data analysis can begin. Reducing real number valued data to a finite string of would destroy fractal structure. If so, the infinitely self-similar structures of fractals in our models might not be such a bad approximation after all.
