Compositional data are nonnegative data carrying relative, rather than absolute, information—
these are often data with a constant-sum constraint on the sample values, for example …

Diet is a key determinant of human gut microbiome variation. However, the fine-scale
relationships between daily food choices and human gut microbiome composition remain …

Epidemiological data suggest that early life exposures are key determinants of immune-
mediated disease later in life. Young children are also particularly susceptible to infections …

Recognition of mineralization-related geochemical footprints and modeling their multi-
element dispersion patterns are important aspects to consider when “vectoring” toward …

Modeling and Analysis of Compositional Data presents a practical and comprehensive
introduction to the analysis of compositional data along with numerous examples to illustrate …

Abstract zCompositions is an R package for the imputation of left-censored data under a
compositional approach. It is pertinent when the analyst assumes that the relevant …

Missing data pose challenges to real-life data analysis. Simple ad-hoc fixes, like deletion or
mean imputation, only work under highly restrictive conditions, which are often not met in …

This paper introduces provenance, a software package within the statistical programming
environment R, which aims to facilitate the visualisation and interpretation of large amounts …

In recent years, the focus of activity behavior research has shifted away from univariate
paradigms (eg, physical activity, sedentary behavior and sleep) to a 24-h time-use paradigm …

This study intends to showcase the application of Extreme Gradient boosting (XGboost), a
state-of-the-art ensemble-learning technique, for district-scale mineral potential mapping …
