On some bivariate copulas

open access: yes, 2010
碩士在第一章,先回顧目前一些二元分佈和二元機率結合函數(Bivariate Copulas)相關的定義、主要定理,及目前的發展概況。接著介紹一些常見的機率結合函數,如AC族、FGM族及常態機率結合函數族。由回顧知道,經由二元機率合函數以建立二元分佈是一項很有用的工具,尤其是邊際分佈為特定分佈時,如邊際分佈為同類型時之二元指數、二元迦瑪等等。 在第二章,本文提出一個新方法以加大二元RULF機率結合函數族,並由調整加大後函數族的參數來提高|ρs|,並加大模型在實際資料的適用範圍。此外地 ...

Testing for Bivariate Spherical Symmetry [PDF]

open access: yes
An omnibus test for spherical symmetry in R2 is proposed, employing localized empirical likelihood. The thus obtained test statistic is distri- bution-free under the null hypothesis. The asymptotic null distribution is established and critical values for

Corporate Environmental Responsibility and Cost of Equity Capital: A Meta‐Analytical Review

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Despite extensive research on the relationship between corporate environmental responsibility (CER) and cost of equity capital (COEC), empirical evidence remains inconsistent. This study addresses these inconsistencies through a comprehensive meta‐analysis of 1139 effect sizes from 75 studies.
