## Inverse Totient Procedure

Exploring two algorithmic approaches for inverting Euler’s Totient function by factorizing Phi.

## Taleb: Statistics and Risk Two Different Businesses

We explore this idea for various probability distributions by looking at the expected loss given that the loss exceeds a certain threshold. We see for fat tails that the expected loss exceeds the threshold itself.

## Taleb: Problems and Inverse Problems Follow-Up

Resolving a discrepancy between my results and Taleb’s in Taleb’s favor, naturally! I had made an assumption that was not implied in his narrative.

## Taleb: Silent Risk Section 3.2 Problems and Inverse Problems

In the real world we generally have only the data and no information about what generated the data. We can go far astray if we make the wrong assumptions.
