Asymptotic minimax risk of predictive density estimation for non-parametric regression

Xinyi Xu, Feng Liang

We consider the problem of estimating the predictive density of future observations from a non-parametric regression model. The density estimators are evaluated under Kullback--Lei…

Improved minimax predictive densities under Kullback--Leibler loss

Edward I. George, Feng Liang, Xinyi Xu

Let $X ∣ μ \sim N_{p} (μ, v_{x} I)$ and $Y ∣ μ \sim N_{p} (μ, v_{y} I)$ be independent p-dimensional multivariate normal vectors with common unknown mean $μ$ . Based on only observing $X = x$ , we consi…
