A general Bayesian model-validation framework based on null-test evidence ratios, with an example application to global 21-cm cosmology
Peter H. Sims, Steven G. Murray, Judd D. Bowman +8
Comparing composite models for multi-component observational data is a prevalent scientific challenge. When fitting composite models, there exists the potential for systematics fro…
A Bayesian approach to modelling spectrometer data chromaticity corrected using beam factors -- I. Mathematical formalism
Peter H. Sims, Judd D. Bowman, Nivedita Mahesh +7
Accurately accounting for spectral structure in spectrometer data induced by instrumental chromaticity on scales relevant for detection of the 21-cm signal is among the most signif…
A Bayesian Calibration Framework for EDGES
Steven G. Murray, Judd D. Bowman, Peter H. Sims +5
We develop a Bayesian model that jointly constrains receiver calibration, foregrounds and cosmic 21cm signal for the EDGES global 21\,cm experiment. This model simultaneously descr…
