Comment:
Remove features already implemented

   * Add more special math functions such as Bessel functions and so on.
   * Add support for iterative linear solvers (see discussion 
[[http://mail-archives.apache.org/mod_mbox/commons-dev/201104.mbox/<20110413062230.2b0e414059...@svoboda.polytechnique.org>|http://mail-archives.apache.org/mod_mbox/commons-dev/201104.mbox/%3c20110413062230.2b0e414059...@svoboda.polytechnique.org%3E]]):
 see wiki page IterativeLinearSolvers
   * Add remedian statistic - 
[[http://www.agoras.ua.ac.be/abstract/Remrob90.htm|The Remedian: a Robust 
Averaging method for Large Data Sets]]
-  * Add ability to compute the density of normal distribution and other well 
behaved distributions (done for some distributions 
https://issues.apache.org/jira/browse/MATH-222)
   * Add ability to sample from some of the common distributions such as 
normal, gamma, beta and so on.
   * Add Dirichlet, Multinomial distributions
-  * Add additional alternative pseudo-random number generators (PRNGs)
   * Investigate alternative methods for generating values from discrete 
distributions http://www.jstatsoft.org/v11/i03/
   * Resampling http://markmail.org/message/u3diwc76m66r7qme
   * Applied-mathematical/Mathematical-physics algorithms? - Henri Yandell

    * [[http://zxg32.blogchina.com/2787280.html|Post-SOC TODO List]] - Xiaogang 
Zhang
   * Implement monte carlo simulation 
http://en.wikipedia.org/wiki/Monte_Carlo_method
   * [[PrimeNumbers|Prime Numbers Functionality]] -- SharonLourduraj
-   * Naive Primality Testing
-   * Probablistic Tests
    * Ofcourse, we will take it slowly, this area is vast and time consuming.
    * Implementing algorithms for practicality, and look into optimizing the 
algorithms (in terms of implementing it).
   * AbstractStorelessUnivariateStatistic.evaluate(...) and all the workhorse 
implementations in subclasses should be static methods. -- NickGuenther
   * StandardDeviation has versions of .evaluate which take a precalculated 
mean. It would be nice if the same sort of thing could be had for all the other 
measures (e.g. skewness & kurtosis should be able to take both precalculated 
means and standard deviations) -- NickGuenther
   * Generalized Matrix Inversion, as I describe on http://mjollnir.com/matrix/ 
-- Rand Huso
   * Estimation of Omega in GLSMultipleLinearRegression using, for example 
Feasible Generalized Least Squares 
http://en.wikipedia.org/wiki/Feasible_generalized_least_squares
-  * Add [[http://en.wikipedia.org/wiki/Convolution|convolution]], 
[[http://en.wikipedia.org/wiki/Laplace_transform|Laplace transform]], 
[[http://en.wikipedia.org/wiki/Z-transform|Z-transform]] and similar 
signal/image processing and filtering related essentials.
+  * Add [[http://en.wikipedia.org/wiki/Laplace_transform|Laplace transform]], 
[[http://en.wikipedia.org/wiki/Z-transform|Z-transform]] and similar 
signal/image processing and filtering related essentials.
   * Add further functionality for BigDecimal and BigInteger arithmetic in 
particular a power function that will input two BigDecimal type numbers and 
raise one to the power of the other and return the result correct to a number 
of specified decimal places. This may best be added to the util.MathUtils class 
along with other pow functions - suggested by Andy Turner (2011-01-20)
   * Add fitter functions for linear models similar to ''lm.wfit'' in 
''R''(2011-11-14)
   * A mixed integer linear programming solver
   * A quadratic programming solver
-  * Implement the Kendall's Tau which is a measure of Association/Correlation 
between ranked ordinal data.[[https://issues.apache.org/jira/browse/MATH-814]]
