(2015) for Canada and seven (China, France, Germany, Japan, Russia, United Kingdom, and United States) other countries to study international uncertainty links by means of a Bayesian Additive Regression Trees (BART) algorithm. Using partial-dependence plots, relative-importance measures, and permutation tests, we shed light on how EPU in Canada is linked to EPU in seven other countries.en© 2016 Elsevier B.V.
