WebJan 2, 2024 · 2 Linear Scalar-on-Function Regression The scalar-response functional linear model can be expressed as y¡ = a + J Xi(t)ß(t)dt + Si, (1) where ß( •) is the coefficient function and errors e i are iid with mean zero and constant variance a2. International … WebJul 18, 2024 · Regressing a scalar response on a random function is nowadays a common situation. In the nonparametric setting, this paper paves the way for making the local linear regression based on a projection approach a prominent method for solving this regression problem. Our asymptotic results demonstrate that the functional local linear regression …

WebApr 23, 2024 · This paper presents tests to formally choose between regression models using different derivatives of a functional covariate in scalar-on-function regression. We demonstrate that for linear regression, models using different derivatives can be nested within a model that includes point-impact effects at the end-points of the observed … Webtion of many scalar-on-function estimation methods. We first focus on estimator selection, or the choice of a single estimator from a large collection of candidates, and then on the dynamic combination of approaches to yield an optimal ensemble estimator of the asso-ciation between a scalar outcome and functional predictor.
