Nonstationary Gaussian Process Models Using Spatial Hierarchical Clustering from Finite Differences

TECHNOMETRICS, 59(1), 93–101.

By: M. Heaton *, W. Christensen * & M. Terres n

author keywords: Geostatistics; Large datasets; Parallel computing; Spatial partition
TL;DR: This work considers partitioning a spatial region into disjoint sets using hierarchical clustering of observations and finite differences as a measure of dissimilarity and proposes a nonstationary Gaussian process model across the clusters, which allows the computational burden of model fitting to be distributed across multiple cores and nodes.

Gibbs posterior inference on the minimum clinically important difference

JOURNAL OF STATISTICAL PLANNING AND INFERENCE, 187, 67–77.

By: N. Syring n & R. Martin n

author keywords: Clinical significance; Loss function; M-estimation; Model-free inference; Posterior convergence rate
TL;DR: A likelihood-free posterior distribution is constructed for the minimum clinically important difference (MCID) and it is shown, numerically, that an appropriately scaled version the posterior yields interval estimates for the MCID which are both valid and efficient even for relatively small sample sizes.
