On marginals and profiled posteriors for cosmological parameter estimation
Martin Kerscher, Jochen Weller
With several examples and in an analysis of the Pantheon+ supernova sample we discuss the properties of the marginal posterior distribution versus the profiled posterior distributi…
Improving the accuracy of estimators for the two-point correlation function
Martin Kerscher
We show how to increase the accuracy of estimates of the two-point correlation function without sacrificing efficiency. We quantify the error of the pair-counts and of the Landy-Sz…
Vec2Sent: Probing Sentence Embeddings with Natural Language Generation
Martin Kerscher, Steffen Eger
We introspect black-box sentence embeddings by conditionally generating from them with the objective to retrieve the underlying discrete sentence. We perceive of this as a new unsu…
On Model Selection in Cosmology
Martin Kerscher, Jochen Weller
We review some of the common methods for model selection: the goodness of fit, the likelihood ratio test, Bayesian model selection using Bayes factors, and the classical as well as…
The Spatial Range of Conformity
Martin Kerscher
Properties of galaxies like their absolute magnitude and their stellar mass content are correlated. These correlations are tighter for close pairs of galaxies, which is called gala…
Morphology of the Local Volume
M. Kerscher, A. Tikhonov
To study the global morphology of the galaxy distribution in our local neighbourhood we calculate the Minkowski functionals for a sequence of volume limited samples within a sphere…
