%description
Methods and tools designed to improve the forecast accuracy for a linearly
constrained multiple time series, while fulfilling the linear/aggregation
relationships linking the components (Girolimetto and Di Fonzo, 2024
<doi:10.48550/arXiv.2412.03429>). 'FoCo2' offers multi-task forecast
combination and reconciliation approaches leveraging input from multiple
forecasting models or experts and ensuring that the resulting forecasts
satisfy specified linear constraints. In addition, linear inequality
constraints (e.g., non-negativity of the forecasts) can be imposed, if
needed.
