The single component geochemical map: Fact or fiction?
Jennifer McKinley,Karel Hron,Eric C. Grunsky,Clemens Reimann,Patrice de Caritat,Peter Filzmoser,Karl Gerald van den Boogaart,Raimon Tolosana-Delgado +7 more
TL;DR: In this paper, the authors investigated the compositional character of geochemical data and proposed two statistical methods to extract potentially interesting geochemical summaries, one based on knowledge-driven log-ratios and the other based on log-contrasts.

Convex Non-negative Matrix Factorization in the Wild
TL;DR: Convex-hull NMF compares favorably to convex NMF for large data sets both in terms of speed and reconstruction quality and it is shown that this method can easily be applied to large-scale, real-world data sets.

Data- and knowledge-driven mineral prospectivity maps for Canada's North
TL;DR: In this article, data-and knowledge-driven techniques are used to produce regional Au prospectivity maps of a portion of Melville Peninsula, Northern Canada using geophysical and geochemical data.

Cowbirds breeding in the central appalachians: spatial and temporal patterns and habitat selection
J. Edward Gates,Daniel R. Evans +1 more
TL;DR: In this article, the authors studied the impact of brood parasitism by female Brown-headed cowbirds (Molothrus ater) on Nearctic-Neotropical migrants.

Tao Zuo,Yang Sun,Yating Wan,Yun Kit Yeoh,Fen Zhang,Chun Pan Cheung,Nan Chen,Juan Luo,Wen Wang,Joseph J.Y. Sung,Paul K.S. Chan,Kunhua Wang,Francis K.L. Chan,Yinglei Miao,Siew C. Ng +14 more
TL;DR: Overall, the gut virome presents more heterogeneity relative to the bacterial microbiome across the examined Chinese populations, with geography carrying the strongest impact and ethnicity-distinct diets associating with certain viral species.

Problems of relative growth
TL;DR: This detailed study of the different rates of growth of parts of the body relative to the body as a whole represents Sir Julian Huxley's great contribution to analytical morphology, and it is still a basis for modern investigations in morphometrics and evolutionary biology.

Experiments with Mixtures: Designs, Models and the Analysis of Mixture Data
TL;DR: In this paper, the original Mixture Problem is described and models for exploring the Entire Simplex Factor Space are presented, including matrix algebra, least squares, and the analysis of variance.
New statistical methods for allometry with application to
TL;DR: In this paper, Mosimann et al. presented new statistical methods for the study of size and shape, and used these methods to study the morphology of red-winged blackbirds, Agelaius phoeniceus breeding in Florida.

Analysis of dispersion on a sphere
TL;DR: In this article, a series of approximate tests of significance is given for hypotheses about the precision constant K and the polar vector on a sphere, where 8' is the angle between the polar and observation vectors.
