Journal ArticleDOI
Spatial analyses of exploration evidence data to model skarn-type copper prospectivity in the Varzaghan district, NW Iran
TL;DR: In this article, two data-driven models of skarn copper prospectivity were generated using logistic regression and random forest techniques, which were then translated to a set of exploration criteria of the deposits in the area.

Sampling epigeal arthropods: an evaluation of fenced pitfall traps using mark‐release‐recapture and comparisons to unfenced pitfall traps in arable crops
John M. Holland,Simon Smith +1 more
TL;DR: The efficiency of fenced pitfall traps for estimating the density of commonly occurring epigeal predatory beetles was examined using mark‐release‐recapture and Rove beetles were more effectively sampled using the fenced compared to unfenced pit fall traps.

Palaeofloristic and palaeovegetational changes across the Paleocene/Eocene boundary in northern South America
TL;DR: In this article, a floral change occurring in northern South America at the Paleocene/Eocene boundary is analysed using palynological data. But, the change is not sudden but stepped and gradual.
Journal ArticleDOI
Self Modeling with Flexible, Random Time Transformations
TL;DR: A SIM is developed that models the time transformations as random, flexible, monotone functions and is applied to speech movement data from the University of Wisconsin X‐ray microbeam speech production project and is motivated byspeech movement data.
Possible solution of some essential zero problems in compositional data analysis
John Aitchison,Jim Kay +1 more
TL;DR: In this paper, an independent binomial conditional logistic normal (ICLN) model and a hierarchical dependent binomial CCLN model are proposed to deal with data sets in which there are components which are essential zeros.

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.
Journal ArticleDOI
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.
