We use the new SNe Ia discovered by the SDSS-II Supernova Survey togetherwith additional supernova datasets as well as observations of the cosmicmicrowave background and baryon acoustic oscillations to constrain cosmologicalmodels. This complements the analysis presented by Kessler et al. in that wediscuss and rank a number of the most popular non-standard cosmology scenarios.When this combined data-set is analyzed using the MLCS2k2 light-curve fitter,we find that more exotic models for cosmic acceleration provide a better fit tothe data than the Lambda-CDM model. For example, the flat DGP model is rankedhigher by our information criteria tests than the standard model. When thedataset is instead analyzed using the SALT-II light-curve fitter, the standardcosmological constant model fares best. Our investigation also includesinhomogeneous Lemaitre-Tolman-Bondi (LTB) models. While our LTB models can bemade to fit the supernova data as well as any other model, the extra parametersthey require are not supported by our information criteria analysis.
