Bayesian evidence and model selection approach for time-dependent dark energy

We use parameterized post-Friedmann (PPF) description for dark energy and apply ellipsoidal nested sampling to perform the Bayesian model selection method on different time-dependent dark energy models using a combination of \(Planck\) and data based on distance measurements, namely baryon acoustic...
