Large-scale MV efficient frontier computation via a procedure of parametric quadratic programming
收藏 引用
EUROPEAN JOURNAL OF OPERATIONAL RESEARCH 2010年 第3期204卷 581-588页
作者: Hirschberger, Markus Qi, Yue Steuer, Ralph E. Univ Georgia Dept Banking & Finance Athens GA 30602 USA Univ Eichstatt Ingolstadt Dept Math Eichstatt Germany Nankai Univ Coll Business Dept Financial Management Tianjin 300071 Peoples R China
Despite the volume of research conducted on efficient frontiers, in many cases it is still not the easiest thing to compute a mean-variance (MV) efficient frontier even when all constraints are linear. This is particu... 详细信息
