Dear Wiki user,

You have subscribed to a wiki page or wiki category on "Commons Wiki" for change notification.

The "MathWishList" page has been changed by monnoo:
http://wiki.apache.org/commons/MathWishList?action=diff&rev1=71&rev2=72

  = Commons-Math Wish List =
  A list of feature requests made by Commons-Math users, contributors, and committers.  These
requests will be considered when deciding on new functionality for future releases.  At any
time, additional feature requests can be added simply by editing this page.
  
+  * Enabling math3.stat for ANY usage in the data mining context, there must be a MissingValues
class that is able to be switched off, to hold a list of missing values, etc. This refers
to any class that imports data (like DescriptiveStatistics or clustering); this is also mandatory
for clustering in real-life contexts (see next entry)
+  * Enabling math3.clustering for ANY reasonable usage in the data mining context, there
must be a small extension for the KNN++ clustering method: a usevector, of the same length
as the variable vector, holding 0|1 and indicating whether a variable (column) should be used:
a working versoin (exhibits also the MissingValues class) is prototypicall available here:

   * 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/<20110413062230.2B0E41405982C@svoboda.polytechnique.org>|http://mail-archives.apache.org/mod_mbox/commons-dev/201104.mbox/%3C20110413062230.2B0E41405982C@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]]
