Abstract: Several recent advances in change point analysis for functional time series are surveyed. Beginning with simple methods to detect and estimate changes in the mean function, we go on to consider change point methods for second-order and higher-order properties of a functional time series. These methods are illustrated with applications time series of curves derived from the energy market and environmental data. We conclude with a discussion of open avenues of research in the area.
