ex machina
"We propose a model for stochastic formation of opinion clusters, modeled by an evolving network, and herd behavior to account for the observed fat-tail distribution in returns of financial-price data. The only parameter of the model is h, the rate of information dispersion per trade, which is a measure of herding behavior. For h below a critical h* the system displays a power-law distribution of the returns with exponential cutoff. However, for h>h* an increase in the probability of large returns is found and may be associated with the occurrence of large crashes. ©2000 The American Physical Society "

“"it is hard to be brave," said piglet, sniffing slightly, "when you're only a Very Small Animal." rabbit, who had begun to write very busily, looked up and said: "it is because you are a very small animal that you will be Useful in the adventure before us."”

this site chronicles the continuing adventures of my son, odin, who was unexpectedly born on the fourth of july at 25 weeks gestation, weighing 1 pound 7 ounces.
he's quite a fighter and you can always send him a postcard to the most current address listed here if you're inspired by his adventures. see the postcard project/google maps mashup to see a map of the postcards.
if you're new, you can browse the archives to catch up. and don't forget to watch a few movies that i made while we were in the neonatal intensive care unit. or if you want the abridged version and you can find a copy, you can read about his adventures in the november 2005 issue of parents magazine.
