Cosmological Analysis with Minuit Exploration of the Likelihood

CAMEL is a high quality software for performing Cosmological Parameters Estimations with current and future data. Written from scratch in pure C++, emphasis was put in building a clean and carefully-designed project that can grow harmoniously with time. The software was largely tested/debugged and used intensively in several publications.

CAMEL incorporates all the latest cosmological likelihoods and gives access to several parameter estimation methods through the same parameter file:

• High quality Maximum Likelihood Estimate (using the Minuit software), aka "best fits"
• Profile likelihoods
• Markov Chain Monte Carlo (MCMC) with an adaptive scheme for faster convergence (or when you don't know a-priori your proposal)

Note that you don't need any C++ skills to use CAMEL (and very little to add you own data). The code is distributed on GitLab
