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.
