Runs\nspecification-curve analysis over a grid of these choices\n(Simonsohn, Simmons and Nelson (2020)\n), with placebo-in-space and\nbootstrap inference for single specifications and placebo\ninference for the curve as a whole, and uses 'xgboost' models\nwith SHAP values (Lundberg and Lee (2017)\n) to show which choices drive\nthe estimates.
