Sound waste management and optimisation of resource recovery require reliable data on
solid waste generation and composition. In the absence of standardised and commonly …

In the life sciences, many measurement methods yield only the relative abundances of
different components in a sample. With such relative—or compositional—data, differential …

In the US, there are more than 163 million dogs and cats that consume, as a significant
portion of their diet, animal products and therefore potentially constitute a considerable …

Applied geochemistry and environmental sciences invariably deal with compositional data.
Classically, the original or log-transformed absolute element concentrations are studied …

The log-ratio approach to compositional data (CoDa) analysis has now entered a mature
phase. The principles and statistical tools introduced by J. Aitchison in the eighties have …

Most data in environmental sciences and geochemistry are compositional. Already the unit
used to report the data (eg, μg/l, mg/kg, wt%) implies that the analytical results for each …

The log-ratio methodology represents a powerful set of methods and techniques for
statistical analysis of compositional data. These techniques may be used for the estimation …

Intramuscular fat (IMF) content and fatty acid composition affect the organoleptic quality and
nutritional value of pork. A genome-wide association study was performed on 138 Duroc …

Our study focuses on the removal of the so-called size effect, related to a different sample
volume and/or concentration. This effect is associated with many types of instrumental …

Single component geochemical maps are the most basic representation of spatial elemental
distributions and commonly used in environmental and exploration geochemistry. However …
