%description
Combine probabilistic forecasts using CRPS learning algorithms proposed in
Berrisch, Ziel (2021) <doi:10.48550/arXiv.2102.00968>
<doi:10.1016/j.jeconom.2021.11.008>. The package implements multiple
online learning algorithms like Bernstein online aggregation; see
Wintenberger (2014) <doi:10.48550/arXiv.1404.1356>. Quantile regression is
also implemented for comparison purposes. Model parameters can be tuned
automatically with respect to the loss of the forecast combination.
Methods like predict(), update(), plot() and print() are available for
convenience. This package utilizes the optim C++ library for numeric
optimization <https://github.com/kthohr/optim>.
