[pool][performance] Source management question

2010-12-24 Thread Phil Steitz
I have found what I think is a bug in GKOP[1] using [performance]. I need the functionality in the Waiter and WaiterFactory classes in o.a.c.performance.pool to build a test case showing the bug. Having these classes available to pool's unit tests would be good. I am not sure what the best appro

Can you use some other package to compute some quantiles for some particular value of alpha? On Fri, Dec 24, 2010 at 7:13 AM, Pavel Ryzhov wrote: > The alpha interval (0, 1) stays untested. >

[math] Monte Carlo engine with 1D path

2010-12-24 Thread Pavel Ryzhov
So, I see that Monte Carlo is on Math wish list. So I've done a quite simple MC engine that uses 1D path generated by underlying stochastic process. It should be easy to extend it to multidimensional paths but it is not in my plans yet. The implementation is inspired by Quantlib project (http:

Hi, I've implemented a Stable random generator based on Chambers-Mallows-Stuck method as it is described in "Handbook of computational statistics: concepts and methods" by James E. Gentle, Wolfgang Härdle, Yuichi Mori But I'm stuck on unit-testing of the generator as I don't have estimators of

Hi Phil, thanks a lot for feedbacks and for mentoring, much more than appreciated. I take advantage to wish you all a Merry Christmas, all the best, Simo http://people.apache.org/~simonetripodi/ http://www.99soft.org/ On Fri, Dec 24, 2010 at 4:32 AM, Phil Steitz wrote: > On Thu, Dec 23, 2010 a
