TL;DR: Nonparametric Econometrics covers all the material necessary to understand and apply nonparametric methods for real-world problems and is the ideal introduction for graduate students and an indispensable resource for researchers.

TL;DR: Crosslinked polymer nanocomposites that contain boron nitride nanosheets have outstanding high-voltage capacitive energy storage capabilities at record temperatures and have been demonstrated to preserve excellent dielectric and capacitive performance after intensive bending cycles, enabling broader applications of organic materials in high-temperature electronics and energy storage devices.

TL;DR: Nonparametric Econometrics as discussed by the authors is an excellent introduction to nonparametric and semiparametric methods for economic analysis. But it does not address the problem of dealing with the presence of discrete variables.

TL;DR: A method for nonparametric regression which admits continuous and categorical data in a natural manner using the method of kernels is proposed, and the asymptotic normality of the estimator is established.

TL;DR: This article shows that cross-validation produces asymptotically optimal smoothing for relevant components, while eliminating irrelevant components by oversmoothing in the problem of nonparametric estimation of a conditional density.
