FoReco and FoRecoML: A Unified Toolbox for Forecast Reconciliation in R

Daniele Girolimetto, Ines Wilms, Jeroen Rombouts, Yangzhuoran Fin Yang

The R packages FoReco and FoRecoML supply a unified framework for forecast reconciliation that jointly handles cross-sectional, temporal, and cross-temporal cases with both linear and machine learning methods.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

The R packages FoReco and FoRecoML address this gap by offering a comprehensive and unified framework. The packages respectively implement classical and regression-based linear reconciliation approaches, and non-linear approaches based on machine learning for cross-sectional, temporal and cross-temporal frameworks.

C2weakest assumption

That existing software lacked comprehensive joint support for cross-sectional, temporal, and cross-temporal reconciliation, and that the new packages correctly implement the referenced methods with sensible defaults while remaining flexible for experts.

C3one line summary

FoReco and FoRecoML are R packages offering a unified toolbox for linear and non-linear forecast reconciliation across cross-sectional, temporal, and cross-temporal hierarchies.
