Dust storms are frequent in many arid and semi-arid regions of the world; they are a significant environmental hazard that impacts human health, agriculture, transportation, and ecosystems, and their frequency and intens...

This paper proposes a simple hierarchical model and a testing strategy to identify intra-cluster correlations, in the form of nested random effects and serially correlated error components. We focus on intra-cluster seri...

This paper proposes new tests for detecting the presence of a unit root in quite general time series models. Our approach is nonparametric with respect to nuisance parameters and thereby allows for a very wide class of w...
