[erlang-questions] Implemented Poisson and Exponential Distribution

[John-Paul Bader]

Hey guys,


I've spent the last couple of days with re-implementing the algorithms 
for taking random samples from the poisson and exponential distribution 
from R's native C implementation.

It was quite the challenge to translate the imperative C code to Erlangs 
functional style, especially the one goto statement.

The Erlang code might still be subject for optimization and I would 
appreciate any feedback on how to improve it.

The C code is included in the Repo for reference and it is implementing 
after two papers which presented highly efficient algorithms for both 
problems.

The code can be found here:

Kind regards,
