Title: Statistical Lineups for Bayesians
Author(s): Susan Vanderplas* and Heike Hofmann
Companies: Iowa State University and Iowa State University
Keywords: Visual Inference; Lineups; Graphics; Bayes Factors

Graphics play a crucial role in statistical analysis and data mining. The lineup protocol for experimentally testing graphics has traditionally used p-values to identify plots which are significantly visually distinct from randomly generated ``distractor" plots, but this approach does not easily facilitate the examination of randomly generated plots to determine the strength of the distractor effect. This study presents a Bayesian approach to visual inference, using Bayes factors to examine the difference in signal strength in two-target statistical lineups.
