cosmogenic_dating

A few IPython notebooks to show examples of inference of exposure times and erosion rates from measured cosmogenic nuclides concentrations vs. depth.

It compares both Bayesian and Frequentist (Maximum Likelihood Estimation) approachs with different optimization and/or sampling algorithms (grid search, non-linear fitting, MCMC...).
