Finding the number of clusters in a dataset: An information-theoretic approach

CA Sugar, GM James - Journal of the American Statistical …, 2003 - Taylor & Francis
… For the datasets of Figures 1(b) and 1(c), our jump method correctly chooses K¤ D G D 6
and K¤ D G D 1. For the iris data, it indicates that either two or three clusters is a reasonable …

Clustering for sparsely sampled functional data

GM James, CA Sugar - Journal of the American Statistical …, 2003 - Taylor & Francis
We develop a flexible model-based procedure for clustering functional data. The technique
can be applied to all types of curve data but is particularly useful when individuals are …

Are clupeid microphagists herbivorous or omnivorous? A review of the diets of some commercially important clupeids

AG James - South African Journal of Marine Science, 1988 - Taylor & Francis
There are two main schools of thought regarding the diet of clupeids, especially those
inhabiting upwelling regions: either that they are herbivorous or that they are omnivorous but …

Variable selection using adaptive nonlinear interaction structures in high dimensions

P Radchenko, GM James - Journal of the American Statistical …, 2010 - Taylor & Francis
… (b,a) for all a and b and all j = k. We don’t include an intercept term in this model, because
we center Y, the f … The assumption we are making is that f ∗ …

Anti-biofilm activity of silver nanoparticles against different microorganisms

…, A Agostinho, EM Sánchez, H Bach, F Ruiz, G James - Biofouling, 2013 - Taylor & Francis
Biofilms confer protection from adverse environmental conditions and can be reservoirs for
pathogenic organisms and sources of disease outbreaks, especially in medical devices. The …

Genetic variation in GIPR influences the glucose and insulin responses to an oral glucose challenge

…, FS Collins, M Cornelis, GJ Crawford, J Delplanque… - Nature …, 2010 - nature.com
Glucose levels 2 h after an oral glucose challenge are a clinical measure of glucose tolerance
used in the diagnosis of type 2 diabetes. We report a meta-analysis of nine genome-wide …

Functional adaptive model estimation

GM James, BW Silverman - Journal of the American Statistical …, 2005 - Taylor & Francis
In this article we are interested in modeling the relationship between a scalar, Y, and a
functional predictor, X(t). We introduce a highly flexible approach called functional adaptive …

Hidden Markov models for longitudinal comparisons

SL Scott, GM James, CA Sugar - Journal of the American Statistical …, 2005 - Taylor & Francis
Medical researchers interested in temporal, multivariate measurements of complex diseases
have recently begun developing health state models, which divide the space of patient …
