WebDownloadable! The practical importance of coherent forecasts in hierarchical forecasting has inspired many studies on forecast reconciliation. Under this approach, so-called base forecasts are produced for every series in the hierarchy and are subsequently adjusted to be coherent in a second reconciliation step. Reconciliation methods have been shown to … WebIn fact, we can find the optimal \(\bm{G}\) matrix to give the most accurate reconciled forecasts. The MinT optimal reconciliation approach Wickramasuriya et al. ( 2024 ) found a \(\bm{G}\) matrix that minimises the total forecast variance of the set of coherent forecasts, leading to the MinT (Minimum Trace) optimal reconciliation approach.
