Nested $\hat R$: Assessing Convergence for Markov chain Monte Carlo when using many short chains

google-research/google-research 25 Oct 2021

Furthermore we use $\mathfrak n \hat R$ to construct a warmup scheme with an adaptive length, allowing users to avoid running their MCMC algorithms longer than necessary.

A large-scale analysis of racial disparities in police stops across the United States

rfordatascience/tidytuesday 18 Jun 2017

We find that black drivers are stopped more often than white drivers relative to their share of the driving-age population, but that Hispanic drivers are stopped less often than whites.

Controlled Discovery and Localization of Signals via Bayesian Linear Programming

amspector100/pyblip 31 Mar 2022

Applying BLiP to existing state-of-the-art analyses of UK Biobank data (for genetic fine-mapping) and the Sloan Digital Sky Survey (for astronomical point source detection) increased resolution-adjusted power by 30-120% in just a few minutes of computation.

The Augmented Synthetic Control Method

ebenmichael/augsynth 23 Jul 2020

Analogous to bias correction for inexact matching, Augmented SCM uses an outcome model to estimate the bias due to imperfect pre-treatment fit and then de-biases the original SCM estimate.

Multilevel Delayed Acceptance MCMC

pymc-devs/pymc 8 Feb 2022

We develop a novel Markov chain Monte Carlo (MCMC) method that exploits a hierarchy of models of increasing complexity to efficiently generate samples from an unnormalized target distribution.
