Subject [jira] Commented: (MATH-176) Getting errors in estimated parameters using Estimator
Date Sat, 19 Jan 2008 22:54:34 GMT

Luc Maisonobe commented on MATH-176:
------------------------------------

The methods have been implemented as of r613474 in the subversion repository.

Please, review what has been done and check the unit tests and the computed values. If additional
tests with reference results could be added, this would be even better.
