Re: [Math] Getting things done

Hi Math3 devs, Is there a consensus on the future of Math3? I rely on the Linear Algebra package and also Stats. Is there major changes planned for those? I have heard some mentions of refactoring going on, but not sure how much would change to the API ... or if it's just implementation details.

Hi Giles, I ran into the same problem. Many months ago I asked about higher order moments in Multivariate Stats. I pulled the code and implemented third and fourth order moments in MVStats. I had to "unprotect" some methods and mostly got everything working. The problem arose (I think) in one of th

Hi, Is a Histogram class in the works? I am currently using org.apache.commons.math3.stat.Frequency to build my own. I think it would be a really useful addition considering how thorough the other statistical classes / methods are in math 3. Thanx, Mike
