added random-number-generator.lisp: base class, cl wrapper, and gsll added GSLL dependency for call GSL's random number generators added draw-bernoulli-bit: same as draw-bernoulli, but returns 0/1 instead of NIL/T bugfix draw-bernoulli: return boolean for integer probabilities instead of 0,1 added tests for bugfix
added tests fixed method next for gsll-rng to return the correct type
…mber generators, these can serve as comparison to test correctness of implementation

Thanks. I am not using CL very much these days so the code is dormant, but if you want to contribute to this library I am happy to give you write access to the repo, just let me know. |

Yes, I'd like write access. Thanks. |
|
Done. I wonder if you could add a full name to your Github account so people can recognize you on mailing lists etc. |
|
Good idea! |

Univariate distributions
I added the Bernoulli, binomial, and geometric distribution; added
draw-poisson; and made a bugfix indraw-bernoulli.Random number generators
I added the possibility to use random number generators other than the one provided by the Common Lisp implementation. This allows users to switch random number generators without switching CL implementation, to seed the random number generator, and ultimately to use
cl-randomfor all their random number needs.By default, all
drawfunctions use*random-state*, so old code relying oncl-randomwill run unchanged.Some simple random number generators were added. The Mersenne Twister is being worked on.
