WebApr 21, 2024 · This paper introduces local linear regression as a useful tool in the setting of scalar-on-function nonparametric regression. It turns out that functional local linear regression, that is, local linear regression when the regressor is a random function, is not only a convenient method of estimating the regression operator.
