BETOC (BayEsian Tools for Observational Cosmology) is aimed to help
the theoretical physicist community investigate cosmological models
using cosmological observational data.
BETOC is a freeware and open source tool
written in the Mathematica
language. The Mathematica
notebooks of BETOC contain documentation, source code and practical
examples with textual and graphical outputs.
Current features of
it is very easy to
modify the theoretical cosmological model, except some cases
which have non-explicit expressions;
the Bayesian statistics
estimate independent parameters and dependent parameters (or functions
of the independent parameters);
graphical output of
3-dimensional, 2-dimensional and 1-dimensional PDFs;
global maximization of
Mathematica 4 and 5 (version 6 is forthcoming).
Each BETOC notebook
definitions of the theoretical cosmological model;
reading of the observational data;
Bayesian tools library;
calculation of the Bayesian PDF;
global maximization of PDF;
PDF visualization in 3 dimensions (if available);
PDF visualization and analysis in 2 dimensions;
PDF visualization in 1 dimension with (independent
and dependent) parameter estimation.
