WebMean-Variance Optimization. Mathematical optimization is a very difficult problem in general, particularly when we are dealing with complex objectives and constraints. However, convex optimization problems are a well-understood class of problems, which happen to be incredibly useful for finance. A convex problem has the following form: minimise ... WebBlack and Litterman’s responded to this situation in the following way: They continue to accept as a good model for choosing an optimal portfolio \(w\).. They want to continue to allow the customer to express his or her risk tolerance by setting \(\delta\).. Leaving \(\Sigma\) at its maximum-likelihood value, they push \(\mu\) away from its maximum … Web当然整个Black-Litterman模型还有很多可以探讨和研究的地方，就不是本文的覆盖范围了。文章旨在对已经了解该模型和贝叶斯公式的同学提供一个框架性的视角，其中的不严谨和粗漏之处还望批评和指正。最后放一张整个模型的逻辑框架，以便从宏观上理解。 how did boys dress in the 70s
