报告摘要:
Inference via simultaneous confidence band (SCB) is investigated for the mean function of stationary functional time series data with infinite moving average structure. A B-spline estimator is proposed for the mean function together with an SCB which is asymptotically correct. Under mild conditions, the B-spline estimator and its accompanying SCB enjoy oracle efficiency in the sense that they are asymptotically equivalent to the counterparts obtained from the random trajectories entirely observed without errors. Simulation studies are carried out which strongly corroborate the asymptotic theory. The use of SCB is illustrated by analyzing an Electro Encephalogram (EEG) data.
