%description
Implementations of the expected shortfall backtests of Bayer and
Dimitriadis (2020) <doi:10.1093/jjfinec/nbaa013> as well as other well
known backtests from the literature. Can be used to assess the correctness
of forecasts of the expected shortfall risk measure which is e.g. used in
the banking and finance industry for quantifying the market risk of
investments. A special feature of the backtests of Bayer and Dimitriadis
(2020) <doi:10.1093/jjfinec/nbaa013> is that they only require forecasts
of the expected shortfall, which is in striking contrast to all other
existing backtests, making them particularly attractive for practitioners.
