The science collection predates Typed Racket - among many other things. It is hand optimized using the fl- and fx- primitives, which were added before Typed Racked, but this misses some optimizations that Typed Racket is able to do. The biggest problem with the hand optimized code is that bugs tend

Hi, I've been using R to solve some machine learning problems, but I'd really prefer to use Racket. In order to do so, I need probability distributions, accurate definitions of some mathematical functions like the Gamma and the log of the Gamma function, a decent plotting library, and a numerical
