Hi Gang, I noted a recent exchange on OLS regarding Math Commons. Thus far I find the Math Commons working flawlessly. I am also working on a project for pure real time financial optimization using the Linear Programming algorithm of Math commons. I designed my code to flip between the QSOPT package and the Math common LP algo to check the robustness and consistency of results. I get exactly same answers in both and that LP is using over 2000 variables and 3000 constraints!
Keep up the good work and I am looking forward to the 'split' between Commons Math and Statistics. Cheers to you all and have a great 2018 Bill Igoe
