ξ Dark Energy · BAO MCMC
Reproducible Bayesian MCMC inference for dark energy model comparison.

Exploratory release
This project is released as v0.1.0-exploratory. The oscillating dark energy model (Ξosc)
shows a marginal preference for non-zero oscillation amplitude, but this is not sufficient
to claim detection. See Known Limitations.
