Do the digits of Pi appear in a random order? If so, the trillions of digits of Pi calculated can serve as a useful random number generator. This post was inspired by this entry on Matt Asher’s blog. Generating pseudo-random numbers is a key piece of much of modern statistical practice, whether for Markov chain Monte Carlo applications or simpler simulations of what raw data would look like
