Forecast reconciliation
http://www.rdhawan.com/ WebThe MinT optimal reconciliation approach Wickramasuriya et al. ( 2024) found a G G matrix that minimises the total forecast variance of the set of coherent forecasts, leading to the MinT (Minimum Trace) optimal reconciliation approach. Suppose we generate coherent forecasts using Equation (11.7).
