Three Steps of HGM
- Finding a holonomic system satisfied by the normalizing constant.
We may use computational or theoretical methods to find it.
Groebner basis and related methods are used.
- Finding an initial value vector for the holonomic system.
This is equivalent to evaluating the normalizing constant and its derivatives
at a point.
This step is usually performed by a series expansion.
- Solving the holonomic system numerically. We use several methods
in numerical analysis such as the Runge-Kutta method of solving
ordinary differential equations and efficient solvers of systems of linear
equations.
Software Packages for HGM
Most software packages are experimental and temporary documents are found in
"asir-contrib manual" (auto-autogenerated part), or
"Experimental Functions in Asir", or "miscellaneous and other documents"
of the
OpenXM documents
or in this folder.
The nightly snapshot of the asir-contrib can be found in the asir page below,
or look up our
cvsweb page.
- Command line interfaces are in the folder OpenXM/src/hgm
in the OpenXM source tree. See
OpenXM distribution page .
- hgm package for R (hgm_*tar.gz, hgm-manual.pdf) for the step 3.
To install this package in R, type in
R CMD install hgm_*.tar.gz
- The following packages are
for the computer algebra system
Risa/Asir.
They are in the asir-contrib collection.
- yang.rr (for Pfaffian systems) ,
nk_restriction.rr (for D-module integrations),
tk_jack.rr (for Jack polynomials),
ko_fb_pfaffian.rr (Pfaffian system for the Fisher-Bingham system),
are for the steps 1 or 2.
- nk_fb_gen_c.rr is a package to generate a C program to perform
maximal Likehood estimates for the Fisher-Bingham distribution by HGD (holonomic gradient descent).
- ot_hgm_ahg.rr (HGM for A-distributions, very experimental).
