rxmc.model_comparison.log_jacobian

rxmc.model_comparison.log_jacobian(constraint) → float

Comparison-space log-Jacobian of a constraint (sum over active points).

log Z_raw = log Z_transformed + log_jacobian: add it to the evidence of a fit performed in a transformed comparison space (e.g. transform=log) before comparing with a fit in raw space. Zero for identity transforms.
