1# pyt8805   请问这个能解决多阶段CVaR吗（建立线性规划模型），谢谢 ，我的QQ ：380618165

These are histogram of portfolio returns, which is used to form the distribution of your portfolio returns and then to estimate the VaR and CVaR through certain models, eg., mean-variance, historical simulation, etc.. I guess, in above graghs, the red part is VaR under the cut point, and the blue bar further depict the conditionalc VaR.
