What's the license on it? Alternatively, perhaps an email to the authors would encourage them to donate it by opening a JIRA issue.On Mar 3, 2009, at 10:17 PM, Jeff Eastman wrote:The problem with using Blog is that it is meant to be a stand-alone simulation environment and we just need two (one really) of its multitude of sampling classes. I also have not been able to compile it into a jar file, nor have I been able to find one. It does not seem to build on my Mac. Uncommons math already has Gaussian; has some good random number generators; and I just need to figure out how to sample from a Beta distribution with it. The implementation seems simple enough: Beta(a, b) = Gam(1, a)/(Gam(1, a)*Gam(1, b)) - but I don't fully understand what I'm doing, yet.Another alternative suggested by Ted is based upon commons math, but it requires some of Ted's personal extensions to support Beta.Jeff Grant Ingersoll wrote:Are they in the Maven repo? If they are, then we can just add the dependency that way.On Mar 3, 2009, at 6:42 PM, Jeff Eastman wrote:Hi Ted,I'm still trying to resolve two external dependencies on the Blog package to get moving again on DP Clustering:import blog.distrib.Beta; import blog.distrib.UnivarGaussian;I notice we already have uncommons math in trunk and so rNorm should be trivial. Can you suggest how to implement rBeta with it? From the API, it is not obvious to me.Jeff
