radvel.fitting.model_comp(post, verbose=False)

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

Returns:
