We review some of the common methods for model selection: the goodness of fit, the likelihood ratio test, Bayesian model selection using Bayes factors, and the classical as well as the Bayesian information theoretic approaches. We illustrate these different approaches by comparing models for the expansion history of the Universe. In the discussion we highlight the premises and objectives entering these different approaches to model selection and finally recommend the information theoretic approach.

  1. Mapping the Universe as a Bianchi I cosmology with Gaia data

    astro-ph.CO 2026-05 unverdicted novelty 5.0

    Gaia quasar proper motions show a significant quadrupole signal matching an axisymmetric Bianchi I anisotropy model, but the amplitude does not increase with redshift as the model requires and the inferred local shear...

  2. Determination of the best dark matter profile for the Milky Way with Gaia DR3 using Bayesian Model Comparison

    astro-ph.GA 2026-05 unverdicted novelty 4.0

    Bayesian comparison of Gaia DR3 rotation curves favors the Einasto dark matter profile over NFW, prefers cored over cuspy profiles, and finds MOND variants provide poorer fits than the best dark matter models.

  3. Search for Annual Modulation in Combined ANAIS 112 and COSINE 100 Data using Bayesian Model Comparison

    hep-ex 2025-12 conditional novelty 4.0

    Bayesian model comparison of combined ANAIS-112/COSINE-100 residuals finds no meaningful support for an annual cosine modulation (ln Bayes factor < 1.2).
