Validate Portfolio

Identify errors for the portfolio specification

Working with a PortfolioMAD object, use functions to identify errors for the portfolio specification.

Objects

PortfolioMAD Create PortfolioMAD object for mean-absolute deviation portfolio optimization and analysis

`checkFeasibility`	Check feasibility of input portfolios against portfolio object
`estimateBounds`	Estimate global lower and upper bounds for set of portfolios

Validate the MAD Portfolio Problem
The portfolio optimization tools have specialized functions to validate portfolio sets and portfolios.

Portfolio Optimization Theory
Portfolios are points from a feasible set of assets that constitute an asset universe.
PortfolioMAD Object Workflow
PortfolioMAD object workflow for creating and modeling a mean-absolute deviation (MAD) portfolio.
When to Use Portfolio Objects Over Optimization Toolbox
The three cases for using Portfolio, PortfolioCVaR, PortfolioMAD object are: always use, preferred use, and use Optimization Toolbox.
