Re: Tyler Lorig's question about programs to numerically calculate the 
fractal dimension of a (real or simulated) data set, using the
Grassberger-Procaccia method -----

Dynamical Software does this (among a large number of other things)
on PC's. DS is a standalone package of numerical routines for 
dynamical systems analysis. Presumably you could call the relevant 
DS routine from Mathematica, but, frankly, you'd get results a 
lot faster to use DS directly from the DOS prompt. DS is currently 
distributed by Academic Computer Specialists in Salt Lake City. 

There are probably other programs out there that also calculate 
fractal dimensions; a year or so ago I saw a beta version of a 
dynamical systems package for Suns, but don't know whether it's ever 
been released.
