2013-03-22 16:24:37 +00:00
Luc Maisonobe 2fa0f1fc97 Clarified origin of the class.
The original comments seemed to show the class was created from
Mixtools, which is GPL code. As per discussion on the JIRA issue
MATH-817 (see https://issues.apache.org/jira/browse/MATH-817), it
appears it is original work and NOT a derived work from Mixtools.
In fact, Mixtools was used mainly to verify the results and generate
some reference data (see the Junit test cases). Neither the code nor the
API from Mixtools were used.

Algorithem for fitting of a multivariate normal distributions mixture
(implemented by Jared Becksfort).
Added "MixtureMultivariateNormalDistribution" class as "syntactic sugar".
Two unit tests are currently set to "@Ignore" (because they rely on "equals"
which the patch did not seem to implement "equals" consistently).

2013-03-19 14:51:30 +00:00
Luc Maisonobe 4e4e8fad43 Added a way to trigger only increasing or decreasing events in ODE.
The method used is completely different from what was suggested in the
request report. It is fully compatible with previous versions and most
importantly has no side effects on users that do not need this feature,
as it is based on an upstream filtering of the event definition
function. The events detection logic is not modified and it fact it does
not even know events are filtered before they are detected.

Phil Steitz 5d5f253240 Made EmpiricalDistribution smoothing kernel pluggable.
To enable subclasses to provide the enclosing distribution's underlying RandomGenerator
to distribution constructors, two more changes were required:
* In EmpiricalDistribution, the RandomDataGenerator field (randomData) was changed
  from private to protected.
* The private getRan() method in RandomDataGenerator returning the underlying
  RandomGenerator was renamed getRandomGenerator and made public.
