#include <IMP/isd/NormalSigmaPCRestraint.h>
Inheritance diagram for IMP::isd::NormalSigmaPCRestraint:A Penalized Complexity prior on sigma of a normal distribution.
The Penalized Complexity (PC) prior on sigma minimizes the complexity (and resulting risk of over-fitting) introduced by deviation from a delta function ( \(\sigma=0\)) to a normal distribution. Its density is
\[ p(\sigma) = \frac{-\log\alpha}{\sigma_u} \alpha^{\sigma / \sigma_u},\]
where \(\sigma_u\) is a user-specified value of \(\sigma\) that indicates a 'tail event', a value that it is unexpected to exceed, and \(\alpha = p(\sigma > \sigma_u)\) is the density in the tail.
