/commons/proper/math/trunk/src/java/org/apache/commons/math/estimation:
AbstractEstimator.java GaussNewtonEstimator.java
Author: luc
Date: Fri Feb 15 02:01:26 2008
New Revision: 627987
URL: http://svn.apache.org/viewvc?rev=627987&view=rev
Log:
improved SOC between AbstractEstimator and its derived classes
(changed fields from protected to private, changed methods to final,
added counter incrementation final method)
