Expected Shortfall Backtest

Create an expected shortfall (ES) backtest model and run suite of ES backtests

Expected shortfall (ES) provides an estimate of the expected loss on days when there is a VaR failure. For more information, see esbacktest, esbacktestbysim, and esbacktestbyde.

Objects

`esbacktest`	Create `esbacktest` object to run suite of table-based expected shortfall (ES) backtests by Acerbi and Szekely
`esbacktestbysim`	Create `esbacktestbysim` object to run simulation-based suite of expected shortfall (ES) backtests by Acerbi and Szekely
`esbacktestbyde`	Create `esbacktestbyde` object to run suite of Du and Escanciano expected shortfall (ES) backtests
