Fig. 9From: Polar motion prediction using the combination of SSA and Copula-based analysisMarginal distribution’s goodness-of-fit test for \({\hbox{PM}}_{x}\) (left) and \({\hbox{PM}}_{y}\) (right). Generalized extreme value distribution is the black curve, green shows the extreme value distribution, and the blue curve is generalized Pareto distributionBack to article page
