%description
The at-Risk (aR) approach is based on a two-step parametric estimation
procedure that allows to forecast the full conditional distribution of an
economic variable at a given horizon, as a function of a set of factors.
These density forecasts are then be used to produce coherent forecasts for
any downside risk measure, e.g., value-at-risk, expected shortfall,
downside entropy. Initially introduced by Adrian et al. (2019)
<doi:10.1257/aer.20161923> to reveal the vulnerability of economic growth
to financial conditions, the aR approach is currently extensively used by
international financial institutions to provide Value-at-Risk (VaR) type
forecasts for GDP growth (Growth-at-Risk) or inflation
(Inflation-at-Risk). This package provides methods for estimating these
models. Datasets for the US and the Eurozone are available to allow
testing of the Adrian et al. (2019) model. This package constitutes a
useful toolbox (data and functions) for private practitioners, scholars as
well as policymakers.
