Simulation-based inference has its own Dodelson-Schneider effect (but it knows that it does)
Jed Homer, Oliver Friedrich, Daniel Gruen
Making inferences about physical properties of the Universe requires knowledge of the data likelihood. A Gaussian distribution is commonly assumed for the uncertainties with a cova…
Cosmology on point: modelling spectroscopic tracer one-point statistics
Beth McCarthy Gould, Lina Castiblanco, Cora Uhlemann +1
The 1-point matter density probability distribution function (PDF) captures some of the non-Gaussian information lost in standard 2-point statistics. The matter PDF can be well pre…
Informed total-error-minimizing priors: Interpretable cosmological parameter constraints despite complex nuisance effects
Bernardita Ried Guachalla, Dylan Britt, Daniel Gruen +1
While Bayesian inference techniques are standard in cosmological analyses, it is common to interpret resulting parameter constraints with a frequentist intuition. This intuition ca…
Bounds on galaxy stochasticity from halo occupation distribution modeling
Dylan Britt, Daniel Gruen, Oliver Friedrich +2
The joint probability distribution of matter overdensity and galaxy counts in cells is a powerful probe of cosmology, and the extent to which variance in galaxy counts at fixed mat…
