Model Comparison

Fit for planets adding one at a time. Save results as list of posterior objects.

Parameters: post (radvel.Posterior) – posterior object for final best-fit solution with all planets verbose (bool) – (optional) print out statistics List of dictionaries with fit statistics. Each value in the dictionary is a tuple with the statistic value as the first element and a description of that statistic in the second element. list of dictionaries
