Likpotential

Likpotential is a coined term used in theoretical discussions to describe a composite measure that combines a likelihood component with a potential-like term. The name is a portmanteau of likelihood and potential, and there is no single, widely accepted definition.

In rough terms, a likpotential function assigns to a model parameter or hypothesis a scalar value intended to reflect both how well the model explains observed data (the likelihood) and how well it conforms to prior constraints or energy-like penalties (the potential).

In practical applications, likpotential ideas appear in energy-based models and certain Bayesian-inspired methods, where the objective to be optimized or the energy function for sampling is formed as a sum of a log-likelihood term and a potential term. It can be used to shape posterior landscapes, encourage exploration, or impose constraints.

Variations exist across disciplines; some authors treat it as a heuristic or metaphor rather than a formal object. Critics point to lack of standard notation, potential confusion with established concepts (likelihood, prior, energy, potential function).
