Select a verb to display maps for that verb. The top map gives the regularzation fraction for the given verb for each county in the continental United States. The bottom map gives the Gi* z-score for each county. Areas that are darker blue (positive z-score) belong to a cluster that has higher regularization than average, and those that are darker red (negative z-score) belong to a cluster that has lower regularization than average. Counties colored black are those that did not have enough data. See Sec. IIIC in the paper for more information.
