Estimating the smoothness of a Gaussian random field from irregularly spaced data via higher-order quadratic variations
Wei-Liem Loh
This article introduces a method for estimating the smoothness of a stationary, isotropic Gaussian random field from irregularly spaced data. This involves novel constructions of h…
A multivariate central limit theorem for randomized orthogonal array sampling designs in computer experiments
Wei-Liem Loh
Let be an integrable function. An objective of many computer experiments is to estimate by evaluating f at a finite number of p…
Some theoretical results on neural spike train probability models
Hock Peng Chan, Wei-Liem Loh
This article contains two main theoretical results on neural spike train models. The first assumes that the spike train is modeled as a counting or point process on the real line w…
Fixed-domain asymptotics for a subclass of Matérn-type Gaussian random fields
Wei-Liem Loh
Stein [Statist. Sci. 4 (1989) 432--433] proposed the Matérn-type Gaussian random fields as a very flexible class of models for computer experiments. This article considers a subcla…
