Monte Carlo techniques, including MCMC and other methods, are widely used and generate sets of samples from a parameter space of interest that can be used to infer or plot quantities of interest. This note outlines methods used the Python GetDist package to calculate marginalized one and two dimensional densities using Kernel Density Estimation (KDE). Many Monte Carlo methods produce correlated and/or weighted samples, for example produced by MCMC, nested, or importance sampling, and there can… Expand

The kalepy package presents a Python KDE implementation designed for broad applicability by including numerous features absent in other packages that improve upon the traditional ‘histogram’ approach. Expand
Cobaya: code for Bayesian analysis of hierarchical physical models
Cobaya is a general-purpose Bayesian analysis code aimed at models with complex internal interdependencies, and includes interfaces to a set of cosmological Boltzmann codes and likelihoods, and automatic installers for external dependencies. Expand
A Flexible Method for Estimating Luminosity Functions via Kernel Density Estimation
We propose a flexible method for estimating luminosity functions (LFs) based on kernel density estimation (KDE), the most popular nonparametric density estimation approach developed in modernExpand
Interpreting Internal Consistency of DES Measurements
Bayesian evidence ratios are widely used to quantify the statistical consistency between different experiments. However, since the evidence ratio is prior dependent, the precise translation betweenExpand
Cosmological parameters from the likelihood analysis of the galaxy power spectrum and bispectrum in real space
We present a joint likelihood analysis of the halo power spectrum and bispectrum in real space. We take advantage of a large set of numerical simulations and of an even larger set of halo mockExpand
Multi-tasking the growth of cosmological structures
Next-generation large-scale structure surveys will deliver a significant increase in the precision of growth data, allowing us to use ‘agnostic’ methods to study the evolution of perturbationsExpand
Do gamma-ray burst measurements provide a useful test of cosmological models?
Context. We study eight different gamma-ray burst (GRB) data sets to examine whether current GRB measurements — that probe a largely unexplored part of cosmological redshift (z) space — can be usedExpand
Limits on Clustering and Smooth Quintessence from the EFTofLSS
We apply the Effective Field Theory of Large-Scale Structure (EFTofLSS) to analyze cosmological models with clustering quintessence, which allows us to consistently describe the parameter region inExpand
The Effective Field Theory of Large-Scale Structure and Multi-tracer
We study the performance of the perturbative bias expansion when combined with the multi-tracer technique, and their impact on the extraction of cosmological parameters. We consider two populationsExpand
Clustering in Massive Neutrino Cosmologies via Eulerian Perturbation Theory
We introduce an Eulerian Perturbation Theory to study the clustering of tracers for cosmologies in the presence of massive neutrinos. Our approach is based on mapping recently-obtained LagrangianExpand
