An interesting sampling method that was covered briefly in my Bayesian statistics course was rejection sampling. Since I have nothing better to do, I thought it would be fun to make an acceptance-rejection algorithm using R. FUN!
The Rejection Sampling method is usually used to simulate data from an unknown distribution. To do this one samples...

About a year ago I was reading Godel, Escher, Bach by Douglas Hofstadter. In a section on recursion he presents a sequence that he calls "A Chaotic Sequence" defined as:Q(n) = Q(n - Q(n - 1)) + Q(n - Q(n - 2)) for n > 2Q(1) = Q(2) =1It's sim...
