  Software tools
   The QUANFRE project: a professional engineering software developed for EDF in collaboration with NOEO, incorporating frequentist and new Bayesian  methods
                                               for the computation of lifetime statistical decision-helping tools. The mathematical code is freeware and written jointly in C / R, to be used
                                               in Windows and Unix operating systems. The packaging software uses the .NET technology.

      The SIMCAB-Bayes project: R/C tools with Excel interfaces for Windows OS for frequentist and Bayesian computation of a prey-predator Bayesian model
                                                 (first version is described here). This is the evolving result of various studies led with biologists from
                                                  Department Fisheries and Oceans Canada and the Institut de Recherche pour le Développement.
                                                 The current version can be downloaded by interested researchers from both organisms using a password. Just send me an email to get it!
