Hubert Holin started the Boost.Math library. The inverse hyperbolic functions,
and the sinus cardinal functions are his.
</p>
<p>
John Maddock started this library, the beta, gamma, erf, polynomial, and
factorial functions are his, as is the "Toolkit" section, and many
of the statistical distributions.
</p>
<p>
Paul A. Bristow threw down the challenge in <a href="http://www2.open-std.org/JTC1/SC22/WG21/docs/papers/2004/n1668.pdf" target="_top">A
Proposal to add Mathematical Functions for Statistics to the C++ Standard
Library</a> to add the key math functions, especially those essential
for statistics. After JM accepted and solved the difficult problems, not
only numerically, but in full C++ template style, PAB implemented a few of
the statistical distributions. PAB also tirelessly proof-read everything
that JM threw at him (so that all remaining editorial mistakes are his fault).

<p>
Xiaogang Zhang worked on the Bessel functions and elliptic integrals for
his Google Summer of Code project 2006.
</p>
<p>
Bruno Lalande submitted the "compile time power of a runtime base"
code.
</p>
<p>
Johan Råde wrote the optimised floating point classification code.
</p>
<p>
Gautam Sewani coded the logistic distribution as part of a Google Summer
of Code project 2008.
</p>
<p>
M. A. (Thijs) van den Berg coded the Laplace distribution. (Thijs has also
threatened to implement some multivariate distributions).
</p>
<p>
Professor Nico Temme for advice on the inverse incomplete beta function.
</p>
<p>
<a href="http://www.shoup.net" target="_top">Victor Shoup for NTL</a>, without which
it would have much more difficult to produce high accuracy constants, and
especially the tables of accurate values for testing.
</p>
<p>
We are grateful to Joel Guzman for helping us stress-test his <a href="http://www.boost.org/tools/quickbook/index.htm" target="_top">Boost.Quickbook</a>
program used to generate the html and pdf versions of this document, adding
several new features en route.
</p>
<p>
Plots of the functions and distributions were prepared in <a href="http://www.w3.org/" target="_top">W3C</a>
standard <a href="http://www.svg.org/" target="_top">Scalable Vector Graphic (SVG)</a>
format using a program created by Jacob Voytko during a <a href="http://code.google.com/soc/2007/" target="_top">Google
Summer of Code (2007)</a>. Since browser support for rendering SVG is
still not universal (Microsoft Internet Explorer, even IE 8 beta, still lacks
native SVG support but can be made to work with <a href="http://www.adobe.com/svg/viewer/install/" target="_top">Adobe's
free SVG viewer</a> plugin), so the SVG files were batch converted to
JPEG using <a href="http://www.inkscape.org/" target="_top">Inkscape</a>.
</p>
<p>
We are also indebted to Matthias Schabel for managing the formal Boost-review
of this library, and to all the reviewers - including Guillaume Melquiond,
Arnaldur Gylfason, John Phillips, Stephan Tolksdorf and Jeff Garland - for
their many helpful comments.
