FoReco
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() |
| Probabilistic reconciliation | |||
MVN: *mvn() | csmvn() | temvn() | ctmvn() |
Sample-based: *smp() | cssmp() | tesmp() | ctsmp() |
Additionally, FoReco provides various functions for different aspects
of forecast reconciliation, including aggregating time series, balancing
hierarchies, computing projection and covariance matrices, and more.
