Local Likelihood Estimation of Complex Tail Dependence Structures, Applied to U.S. Precipitation Extremes
复杂尾部依赖结构的局部似然估计：美国极端降水应用
To disentangle the complex nonstationary dependence structure of precipitation extremes over the entire contiguous United States (U.S.), we propose a flexible local approach based on factor copula models. Our subasymptotic spatial modeling framework yields nontrivial tail dependence structures, with a weakening dependence strength as events become more extreme; a feature commonly observed with precipitation data but not accounted for in classical asymptotic extreme-value…
