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

18 Jun 2017rfordatascience/tidytuesday

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.

Model Class Reliance: Variable Importance Measures for any Machine Learning Model Class, from the "Rashomon" Perspective

4 Jan 2018ModelOriented/DrWhy

Expanding on MR, we propose Model Class Reliance (MCR) as the upper and lower bounds on the degree to which any well-performing prediction model within a class may rely on a variable of interest, or set of variables of interest.

A Conceptual Introduction to Hamiltonian Monte Carlo

10 Jan 2017tpapp/DynamicHMC.jl

Hamiltonian Monte Carlo has proven a remarkable empirical success, but only recently have we begun to develop a rigorous under- standing of why it performs so well on difficult problems and how it is best applied in practice.

nflWAR: A Reproducible Method for Offensive Player Evaluation in Football

3 Feb 2018ryurko/nflscrapR-data

We discuss how our reproducible WAR framework, built entirely on publicly available data, can be easily extended to estimate WAR for players at any position, provided that researchers have access to data specifying which players are on the field during each play.
