估计收益率的均值和协方差

评估投资组合资产收益率的均值和协方差，包括含缺失数据和金融时间序列数据的资产

在使用 Portfolio 对象的情况下，使用函数评估投资组合资产收益的均值和协方差，包括含缺失数据和金融时间序列数据的资产。

对象

Portfolio 创建 Portfolio 对象以进行均值-方差投资组合优化和分析

函数

`getAssetMoments`	从 Portfolio 对象获取资产收益的均值和协方差
`setAssetMoments`	设置 Portfolio 对象资产收益的矩（均值和协方差）
`estimateAssetMoments`	Estimate mean and covariance of asset returns from data
`setCosts`	Set up proportional transaction costs for portfolio

Asset Returns and Moments of Asset Returns Using Portfolio Object
Mean-variance portfolio optimization problems require estimates for the mean and covariance of asset returns.
Working with a Riskless Asset
The Portfolio object uses a separate RiskFreeRate property that stores the rate of return of a riskless asset.
Working with Transaction Costs
The difference between net and gross portfolio returns is transaction costs.
Asset Allocation Case Study
This example shows how to set up a basic asset allocation problem that uses mean-variance portfolio optimization with a Portfolio object to estimate efficient portfolios.
使用 Financial Toolbox 的投资组合优化示例
通过一组示例来了解 Portfolio 对象的主要功能。具体来说，这些示例使用 Portfolio 对象来展示如何设置重点关注两基金分离定理、交易成本和换手率约束影响的均值-方差投资组合优化问题，如何获取最大化夏普比率的投资组合，以及如何建立两种流行的对冲基金策略（美元中性和 130/30 投资组合）。
Leverage in Portfolio Optimization with a Risk-Free Asset
This example shows how to use the setBudget function for the Portfolio class to define the limits on the sum(AssetWeight_i) in risky assets.
Portfolio Optimization with Semicontinuous and Cardinality Constraints
This example shows how to use a Portfolio object to directly handle semicontinuous and cardinality constraints.
Black-Litterman Portfolio Optimization Using Financial Toolbox
This example shows the workflow to implement the Black-Litterman model with the Portfolio class in Financial Toolbox™.
Portfolio Optimization Using Factor Models
This example shows two approaches for using a factor model to optimize asset allocation under a mean-variance framework.
Portfolio Optimization Using Social Performance Measure
Use a Portfolio object to minimize the variance, maximize return, and maximize the average percentage of women on a company's board.
