Robust and Accurate Inference via a Mixture of Gaussian and Student's t Errors
JOURNAL OF COMPUTATIONAL AND GRAPHICAL STATISTICS, 28(2), 415–426.
author keywords: Gaussian process; Gibbs sampling; Hierarchical model; Huber's M-estimator; Linear mixed model; Outlier; Time series
TL;DR:
A mixture error assumption is proposed that selectively converts Gaussian errors into Student's t errors according to latent outlier indicators, leveraging the best of the Gaussian and Student’s t errors; a parameter estimation can be not only robust but also accurate.

Discussion of "Penalized Spline of Propensity Methods for Treatment Comparison" by Zhou, Elliott, and Little
Yang, S., & Zeng, D. (2019, January 2). JOURNAL OF THE AMERICAN STATISTICAL ASSOCIATION, Vol. 114, pp. 31–32.
TL;DR:

Bayesian mode and maximum estimation and accelerated rates of contraction
BERNOULLI, 25(3), 2330–2358.
author keywords: anisotropic Holder space; credible set; maximum value; mode; nonparametric regression; posterior contraction; sequential; tensor-product B-splines; two-stage
TL;DR:
