Abstract
Recent astronomical observations indicate that our universe is undergoing a period of accelerated expansion. While there are many cosmological models that explain this phenomenon, the main question remains which is the best one in light of available data. We consider 10 cosmological models of the accelerating universe and select the best one using the Bayesian model comparison method. We demonstrate that the ΛCDM model is most favored by the Bayesian statistical analysis of the SNIa, CMB, baryon acoustic oscillation, and H(z) data.
