广义分位数的渐近性质
The Asymptotic Properties of Generalized Quantiles
【摘要】 Bellini等人提出了广义分位数并研究了其基本性质,特别针对重尾分布分析了期望分位数与一般分位数的渐近关系.本文在假设广义分位数为正规变化函数的基础上,研究广义分位数与一般分位数的渐近关系.
【Abstract】 Bellini et al.(2014) proposed the generalized quantile and studied its basic properties. In particular, for heavy-tailed distributions, the paper also analyzed the asymptotic relationship between expectiles and quantiles. Based on the assumption that the generalized quantile is a regularly varying function, this paper studies its asymptotic relationship with quantiles.
