The approach that we adopt is based on functional kernel nonparametric regression estimation techniques where observations are discrete recordings of segments of an underlying stochastic process considered as curves. These curves are assumed to lie within the space of continuous functions, and the discretized time series data set consists of a relatively small, compared with the number of segments, number of measurements made at regular times. We estimate conditional expectations by using appropriate wavelet decompositions of the segmented sample paths. A notion of similarity, based on wavelet decompositions, is used to calibrate the prediction. Asymptotic properties when the number of segments grows to \u221e are investigated under mild conditions, and a nonparametric resampling procedure is used to generate, in a flexible way, valid asymptotic pointwise prediction intervals for the trajectories predicted. We illustrate the usefulness of the proposed functional wavelet\u2013kernel methodology in finite sample situations by means of a simulated example and two real life data sets, and we compare the resulting predictions with those obtained by three other methods in the literature, in particular with a smoothing spline method, with an exponential smoothing procedure and with a seasonal autoregressive integrated moving average model.<\/jats:p>","DOI":"10.1111\/j.1467-9868.2006.00569.x","type":"journal-article","created":{"date-parts":[[2006,10,24]],"date-time":"2006-10-24T15:34:04Z","timestamp":1161704044000},"page":"837-857","source":"Crossref","is-referenced-by-count":106,"title":["A Functional Wavelet\u2013Kernel Approach for Time Series Prediction"],"prefix":"10.1093","volume":"68","author":[{"given":"Anestis","family":"Antoniadis","sequence":"first","affiliation":[{"name":"Joseph Fourier University , Grenoble , France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Efstathios","family":"Paparoditis","sequence":"additional","affiliation":[{"name":"University of Cyprus , Nicosia , Cyprus"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Theofanis","family":"Sapatinas","sequence":"additional","affiliation":[{"name":"University of Cyprus , Nicosia , Cyprus"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2006,10,24]]},"reference":[{"key":"2023040708372495400_","doi-asserted-by":"crossref","first-page":"133","DOI":"10.1016\/S0047-259X(03)00028-9","article-title":"Wavelet methods for continuous-time prediction using Hilbert-valued autoregressive processes","volume":"87","author":"Antoniadis","year":"2003","journal-title":"J.
