We perform a full Bayesian analysis of both inflation parameters and cosmological parameters taking reheating into account self-consistently. We compute the Bayesian evidence for a few representative inflation scenarios in both the standard $\\Lambda$CDM model and an extension including dark radiation parametrised by its effective number of relativistic species $N_\\mathrm{eff}$.
