Statistical Consequences of Fat Tails

Taleb discusses how fat tails can affect probabilities. Is a 10 sigma event an outlier or is it part of a different power law distribution. How slowly does the Central limit theorem conform say Student T distribution to normal (need n>120) for proper confidence levels. Learned about Pareto and other power law distributions. Book suffered from poor editing, missing color references, and Taleb's abrasive pedantics. Recommended nonetheless.

I have learned a lot from both Vic & Taleb. Vic introduced me to obscure trading psychology & insights. Via his books, interviews and books recommended (Horse Trading, Secrets of Professional Turf Betting etc). At first these recommendations seemed strange. But after watching this video by D. E Shaw, it finally made sense because Shaw hints that successful models are built often via thinking in terms of analogies. So, reading Vic's own books, book reccomdations and thinking in terms of analogies can allow you to develop new insights into the market.

Taleb introduced me to the complexity theorists (Didier Sornette, Ole Peters, Mandelbrot etc). He also actually introduced me to Vic's work. Education of a Speculator is praised & highly recommend in Taleb's Fooled by Randomness. I also like Taleb, because he simplifies his concepts in to plain English. So a lay man like me can easily understand what he is trying to say. For instance majority of a statistical consequences of fat tails is summarized in Extreme events and how to live with them- The Darwin College Lecture. In plain English.

Zubin Al Genubi reponds:

The gist of the papers is that use of Gaussian underestimates tail events. Its a good point. Since so many do, it opens good trading opportunity. I've found several which is left as an exercise for the reader and explained in the references here.
