Distributions, Tools for Data Fitting to Univariate Distributions and Tools for 1D and 2D Monte-Carlo Simulations.
An R package project for fitting distributions, assessing variability and uncertainty in the context of food safety modelling. The downloads are available at R-Forge. These tools were imagined and written by Régis Pouillot and Marie-Laure Delignette.
Manipulation of Bayesian networks within R : the starting manual, the set of files (with Rd documentation in pdf) [if you want to get announcements of new releases, just ask for it by e-mail].
Standardizing general comments in R functions and extracting them to produce manual files : description of the format, Perl script. The improvements of this last version are due to Régis Pouillot.
This script is used in another script to automatically produce R packages. The name is paquet.pl, some details are given in its comments. It was built for the generation of RebaStaBa.
If you want to try it with a complete example, just save and expand pr.zip. A named paquet directory will be
created including comment.pl and paquet.pl and the necessary
files into a perso directory for the package rs00 of
the miscellaneous utility functions of rebastaba (you can find some of them of
use too). To check the package and build its documentation pdf file, just type
from the paquet directory paquet.pl rs00 cd.
When using Jags you can produce outputs too large for reading them in R. As it is not that simple to know in advance which size to give to the burnin phase and which thinning frequency to use in advance, one can be obliged to run several times the same MCMC. Using jaxtrai.pl allows you to handle much larger outputs.
Modelling interaction between two factors was a main focus of my research activities many years ago when I was collaborating with plant geneticists interpreting genotype by environment interactions. INTERA, written with the late Guy Decoux, is a set of Pascal programs running on DOS. To use them you need to know how to edit a text file (kind of script files) and how to launch from a terminal this kind of programs. You can get the binaries of the programs or the binaries and soures and documentations in zipped files. Unfortunately, except an extended summary, the main part of the manual is written in French.
More recent development was undertaken in SPlus with the BiaReg project. Source files are available, also is a companion manual. The flaw is that BiaReg does not deal with missing values. It is not so much work to encapsulate BiaReg with an EM or ALS algorithm, Vincent Foucteau did it during his PhD but this was never published.
I cannot give any help about the use of intera or biareg.
