Web1 Introduction. This paper studies regression with a functional predictor and a scalar response. Suppose one observes data {(X i (t), Y i) : t ∈ τ} for i = 1, …, N, where X i is a real-valued, continuous, square-integrable, random curve on the compact interval τ and Y i is a scalar.We assume that the predictor, X(·), is observed at a dense grid of points.
