BETOC

(BayEsian Tools for Observational Cosmology )

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.

Description

Current features of BETOC :

it is very easy to modify the theoretical cosmological model, except some cases which have non-explicit expressions;
the Bayesian statistics allows to 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 PDF;
compatible with Mathematica 4 and 5 (version 6 is forthcoming).

Each BETOC notebook contains :

definitions of the theoretical cosmological model;
reading of the observational data;
chi^2 definition;
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.
