A sliced Wasserstein and diffusion approach to random coefficient models
Keunwoo Lim, Ting Ye, Fang Han
We propose a new minimum-distance estimator for linear random coefficient models. This estimator integrates the recently advanced sliced Wasserstein distance with the nearest neigh…

Smoothed NPMLEs in nonparametric Poisson mixtures and beyond
Keunwoo Lim, Fang Han
We discuss nonparametric mixing distribution estimation under the Gaussian-smoothed optimal transport (GOT) distance. It is shown that a recently formulated conjecture -- that the…
