Here's my idea for approximating derivatives. It follows the decorator layout of commons-collections. The main interface point is the UnivariateRealFunctionUtils type which is responisble for creating decorated UnivariateRealFunction objects. To demostrate the how the decorators could be used, I added the UnivariateRealFunctionUtilsTest class which computes a local maximum of a function using derivative decorators and the default solver.

Rewrite StatUtils to use static instances of UnivariateStatistics. Benefits?
...
1.) In the future, when we establish "Factories" for these objects, we'll be able to plug implementations in, even under our static Utilities classes for these functions.
2.) The user can always rely on the same result, whether using the StaticUtil, Univariate Container or direct UnivariateStatistic.

checks if the internal state of the underlying statistic has changed

because it is only returning a property value.

This house-cleaning improves UnivariateImpl, in a number of ways.
...
1.) insertValue is abolished and its contents are now in addValue
2.) UnivariateImpl now extends AbstractStoredUnivariate to deligate to
those methods directly for calculating statistics when storage is active, all methods
deligate to AbstractStoreUniv when the DoubleArray is no longer null. This also means
that a majority of the StoreUnivariate interface is now implemented in Univariate to provide
deligates when storage is active, and to throw runtime exceptions when its not (this at least until
we establish rolling implementations for those methods). We should consider consolidating the
StoreUnivariate interface into the Univariate interface
3.) Calculations in addValue have been reorganized, only calculations for
the storageless solution are now present in this class. otherwise the value is
added/Rolling to the Double array when appropriate.
I'm satisfied that it passes all Unit tests.

I added this, but there are changes I'd like to make in the near future. Only the "running" aspects of the variance calc should be in the insertValue function, all other calculation should be in the getVariance function.

Addition of a BeanListUnivariateImpl which can gather univariate statistics on a
...
List of JavaBeans. This implementation extends the ListUnivariateImpl, and uses the
PropertyUtils classes from commons-beanutils. With this implementation, the following
is possible:
List persons = new ArrayList();
// populate array with 100 persons
Univariate ageU = new BeanListUnivariateImpl( persons, "age" );
Univariate incomeU = new BeanListUnivariateImpl( persons, "jobInfo.income" );
System.out.println( "Mean age is: " + ageU.getMean() );
System.out.println( "Mean income is: " + incomeU.getMean() );
Better error handling is needed near our use of PropertyUtils.
This patch introduces a dependency on commons-beanutils, which in turn depends
on commons-collections and commons-logging.

* a distribution factory following the abstract factory pattern.
The value being, if users want to swap out the default distribution
implementations with their own, why stop them. The factory is responsible for
create the distribution instances (only continuous ones for now).
* Each distribution has a cummulativeProbabilty method which returns the value of
the CDF for a given value. By default, via the abstract distribution base
class, an inverseCummulativeProbability method is all provided for all
distributions. It's implementation is generically handled by applying root
finding techniques to the cummulativeProbability method. That way, when new
distributions are added, authors only need to create the CDF method and the
inverse is provided automatically.
* Currenty, the only distributions are Chi-Squared and Gamma (one actually since
Chi-Squared is a specialized Gamma) but more are planned.
