A comparison of Bayesian and frequentist confidence intervals in the presence of a late Universe degeneracy

Abstract Hubble tension is a problem in one-dimensional (1D) posteriors, since local $$H_0$$ H 0 determinations are only sensitive to a single parameter. Projected 1D posteriors for $$\Lambda $$ Λ CDM cosmological parameters become more non-Gaussian with increasing effective redshift when the model...
