Debiasing inference in large-scale structure with non-flat volume measures
Alexander Reeves, Pierre Zhang, Henry Zheng
Increasingly large parameter spaces, used to more accurately model precision observables in physics, can paradoxically lead to large deviations in the inferred parameters of intere…
