A. Harvey et Sj. Koopman, FORECASTING HOURLY ELECTRICITY DEMAND USING TIME-VARYING SPLINES, Journal of the American Statistical Association, 88(424), 1993, pp. 1228-1236
A method for modeling a changing periodic pattern is developed. The us
e of time-varying splines enables this to be done relatively parsimoni
ously. The method is applied in a model used to forecast hourly electr
icity demand, with the periodic movements being intradaily or intrawee
kly. The. full model contains other components, including a temperatur
e response, which is also modeled using splines.
