Optimal forecast reconciliation
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. WebMar 14, 2024 · That should not come as a surprise, as the optimal reconciliation approach is known to provide the most accurate forecasts (for more information about its advantages, please see the previous article). There is also one thing that we should be aware of — the OLS approach created a negative fitted value for the first observation.

WebHyndman, Ahmed, Athanasopoulos, & Shang (2011) developed a method that they call “optimal reconciliation”, which handles forecasts for grouped or hierarchical structures. First, independent forecasts are generated for all nodes at every level of the hierarchy, and then an optimal reconciliation step is used to adjust the forecasts. WebOct 6, 2024 · Temporal reconciliation was proposed by Athanasopoulos et al. ( 2024). Here it is in our new notation. For simplicity we will assume the original (scalar) time series is observed with a single seasonality of period m m (e.g., m=12 m = 12 for monthly data), and the total length of the series T T is an integer multiple of m m.
