10.9 Further reading

There are no other textbooks which cover hierarchical forecasting in any depth, so interested readers will need to tackle the original research papers for further information.

• Gross & Sohl (1990) provide a good introduction to the top-down approaches.
• The reconciliation methods were developed in a series of papers, which are best read in the following order: Hyndman et al. (2011), Athanasopoulos et al. (2009), Hyndman, Lee, & Wang (2016), Wickramasuriya et al. (2019).
• Athanasopoulos, Hyndman, Kourentzes, & Petropoulos (2017) extends the reconciliation approach to deal with temporal hierarchies.
