On Modeling and Forecasting Time Series of Smooth Curves

Summary: [This abstract is based on the author’s abstract.] A methodology is proposed for forecasting time series of smooth curves by combining functional data analysis with time series factor models. The study is motivated by a business application of forecasting future call arrival rate profiles to telephone customer service center. There are three parts to the proposed methodology: dimension reduction through a smooth factor model, time series modeling and forecasting of the factor scores, and dynamic updating using penalized least squares.
