%description
We provide a toolbox to conduct a Bayesian meta-analysis for estimating
the current expansion rate of the Universe, called the Hubble constant H0,
via time delay cosmography. The input data are Fermat potential difference
and time delay estimates. For a robust inference, we assume a Student's t
error for these inputs. Given these inputs, the meta-analysis produces
posterior samples of the model parameters including the Hubble constant
via Metropolis-Hastings within Gibbs. The package provides an option to
implement repelling-attracting Metropolis-Hastings within Gibbs in a case
where the parameter space has multiple modes.
