Hi, I have been looking for fractal behavior in a data set. I've used the box method to determine fractal dimension by looking at the inverse of box size and the number of boxes needed to enclose the object. These two variables seem to be fairly accurately predicted by a power law (exponent/fractal dimension around 1.85) but I was hoping for a simple statistical method that explicitly looks for self similarity on different scales. Does anyone have any ideas here? Thanks in advance for any help.
