What do people here use when they need statistics. I am specialliy 
interested in Probability Kernel Density functions.

Hi,
You may want to have a look at MathPaqs:
  http://sf.net/projects/mathpaqs/
there is a "samples" packages in the stats subdirectory.
No KDE so far, though, just plain histograms.
There are also some random simuation tools.

Thanks

That may bee just what i need. I have decide to
make the KDE my self the math is not that awful,
The formulas are at at Wikipedia and most of what
i need is in Ada.numerics. I take look at
Mathpags to see if there some useful stuff for me there.

If you need asymmetric matrices, you might find Ada 2005 Math Extensions
useful.

Out of curiosity: it is presented as Gnat-specific. Why?

It used to use Interfaces.Fortran.BLAS, which was removed in GNAT GPL
2012/GCC 4.7. AdaCore reimplemented Ada.Numerics to improve portability
(to systems that don't have BLAS, LAPACK) at the expense of performance.

The body of Ada_Numerics.Generic_Arrays now says

   with Interfaces.Fortran;
   with System.Generic_Array_Operations;

and I think the latter is a GNAT unit? (of course, anyone could copy it;
it doesn't look unusual aside from a pragma Inline_Always).

Also, I don't have any other Ada 2005 compiler!


The library needs BLAS and LAPACK, easy enough on Mac OS X and Debian,
apparently a PITA on Windows.
