So I checked on these. The non-trivial issues with replacing Commons Math include:
- Poisson and negative binomial distributions. This would be several hours work to write and test (we have Colt-inherited negative binomial distribution, but it takes no longer to write a new one than to test an old one). - random number generators. This is about and hour or two of work to pull the MersenneTwister implementation into our code. - next prime number finder. Not a big deal to replicate, but it would take a few hours to do. - quadrature. We use an adaptive integration routine to check distribution properties. This, again, would take a few hours to replace. I really don't see the benefit to this work.
