Hi list,

I'm glad to announce the release of Langhua LearningCurve component for
OFBiz. 

License:
The LearningCurve component is in LGPL 3.0 license.

Develop Environment:
The LearningCurve component is developed and tested with OFBiz trunk on
Fedora 10 x86_64, OpenJDK 1.6.

Background:
The LearningCurve component is an algorithm module without UI. It's
developed for our internal project management system. We want to match
the CMM4. We have to find a way to estimate work efforts from our
history data and set shield. As we are a service company, we believe
Learning Curve theory is the key to build up our PMS.

References:
We referenced the following sources during the development:

http://en.wikipedia.org/wiki/Linear_regression

(Personally, I think it would be great if Apache has a TPL like Jama.
Jama seems dead.)

You can run the test cases in Eclipse to see the results. If you find
any bug or have any suggestion on this component, please feedback to me.

Enjoy it.
