Partition function approach to non-Gaussian likelihoods: information theory and state variables for Bayesian inference

Rebecca Maria Kuntz, Heinrich von Campe, Tobias Röspel +2

The significance of statistical physics concepts such as entropy extends far beyond classical thermodynamics. We interpret the similarity between partitions in statistical mechanic…

Partition function approach to non-Gaussian likelihoods: macrocanonical partitions and replicating Markov-chains

Maximilian Philipp Herzog, Heinrich von Campe, Rebecca Maria Kuntz +2

Monte-Carlo techniques are standard numerical tools for exploring non-Gaussian and multivariate likelihoods. Many variants of the original Metropolis-Hastings algorithm have been p…

Partition function approach to non-Gaussian likelihoods: partitions for the inference of functions and the Fisher-functional

Rebecca Maria Kuntz, Maximilian Philipp Herzog, Heinrich von Campe +2

Motivated by constraints on the dark energy equation of state from supernova-data, we propose a formalism for the Bayesian inference of functions: Starting at a functional variant…

Partition function approach to non-Gaussian likelihoods: physically motivated convergence criteria for Markov-chains

Lennart Röver, Heinrich von Campe, Maximilian Philipp Herzog +2

Non-Gaussian distributions in cosmology are commonly evaluated with Monte Carlo Markov-chain methods, as the Fisher-matrix formalism is restricted to the Gaussian case. The Metropo…
