Optimally reconciling forecasts in a hierarchy

 

This is an introduction to our approach to forecast reconciliation without using any matrices. The original research is available here:

• Hyndman, Ahmed, Athanasopoulos and Shang (CSDA, 2011)
• Athanasopoulos, Ahmed and Hyndman (IJF, 2009)

The software is available in the hts package for R with some notes on usage in the vignette. There is also a gentle introduction in our forecasting textbook.
