Nonparametric Functional Least Absolute Relative Error Regression: Application to Econophysics

In this paper, we propose an alternative kernel estimator for the regression operator of scalar response variable <i>S</i> given a functional random variable <i>T</i> that takes values in a semi-metric space. The new estimator is constructed through the minimization of the least absolute relative er...
