Robust Estimation of <i>L</i><sub>1</sub>-Modal Regression Under Functional Single-Index Models for Practical Applications

Robust Estimation of <i>L</i><sub>1</sub>-Modal Regression Under Functional Single-Index Models for Practical Applications

We propose a robust procedure to estimate the conditional mode of a univariate outcome <i>O</i> given a Hilbertian explanatory variable <i>I</i>, under the assumption that <inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML" display="inline...
