Influence diagnostics for the structural sharpe model under normal/independent distributions
收藏 引用
COMMUNICATIONS IN STATISTICS-THEORY AND METHODS 2019年 第8期48卷 1815-1835页
作者: Zeller, Camila Borelli Vilca, Filidor Galea, Manuel Univ Fed Juiz de Fora Dept Estat Juiz De Fora MG Brazil Univ Estadual Campinas Dept Estat Sao Paulo Brazil Pontificia Univ Catolica Chile Dept Estadist Santiago Chile
A method is proposed in this paper to assess the local influence of minor perturbations for the Sharpe model when the normal distribution is replaced by normal/independent (NI) distributions. The family of NI distribu... 详细信息
