Invited Article: Second Akaike Memorial Lecture

I am most grateful to the invited discussants, Professor Chris Glynn and Dr. Jouchi Nakajima, for their thoughtful and constructive comments and questions. Their discussion contributions speak clearly to some of the key areas of advance in Bayesian forecasting and time series modeling reviewed in the paper, and critically address important areas of “Challenges and Opportunities” with some new suggestions and connections. My responses here speak directly to their specific comments and questions. I hope and expect that this conversation will additionally contribute to promoting new research developments in dynamic models for increasingly complex and challenging problems in multivariate time series analysis and forecasting—and the broader fields of statistical modeling and decision analysis—in the Akaike tradition.

The discussants focus primarily on issues of model structure specification and learning in dynamic graphical models. These issues raise hard questions in multivariate models...
