A three-day workshop about accurate post-selection inference, with emphasis on foundations, theory and methods, and important applications. Topics include: selective and simultaneous inference, high-dimensional inference, and Bayesian post-selection inference. Also considered are tools from higher-order asymptotics, including analytic and simulation-based refinements, to improve accuracy and power for post-selection inference procedures. More than 20 invited talks, and two poster sessions. Registration opens in early 2017.
