Forecast Reconciliation is a a post-forecasting process aimed to improve the accuracy and align forecasts for a system of linearly constrained (e.g. hierarchical/grouped) time series. The FoReco package provides a comprehensive set of classical (bottom-up, top-down and middle-out), and modern (optimal and heuristic combination) forecast reconciliation procedures in different frameworks including cross-sectional, temporal, or cross-temporal settings.
The core functions for reconciliation categorized by framework are as follows:
| Reconciliation | Cross-sectional | Temporal | Cross-Temporal |
|---|---|---|---|
| Classical reconciliation | |||
Top-down: *td() |
cstd() |
tetd() |
cttd() |
Bottom-up: *bu() |
csbu() |
tebu() |
ctbu() |
Middle-out: *mo() |
csmo() |
temo() |
ctmo() |
| Regression‑based reconciliation | |||
Least squares: *rec() |
csrec() |
terec() |
ctrec() |
LCC: *lcc() |
cslcc() |
telcc() |
ctlcc() |
Additionally, FoReco provides various functions for different aspects of forecast reconciliation, including aggregating time series, balancing hierarchies, computing projection and covariance matrices, and more.
You can install the stable version on R CRAN
