Microbiome Datasets Are Compositional: And This Is Not Optional [PDF]

open access: yesFrontiers in Microbiology, 2017
Datasets collected by high-throughput sequencing (HTS) of 16S rRNA gene amplimers, metagenomes or metatranscriptomes are commonplace and being used to study human disease states, ecological differences between sites, and the built environment.

Compositional data analysis

Occupational and Environmental Medicine, 2020
Recently, Keskitalo et al presented a study focused on the association of bronchoalveolar lavage fluid (BALF) cell differential counts (CDCs) with the smoking habits and the number of asbestos bodies (ABs) in a population of patients with asbestosis.1 They also dealt with the dependence between the survival time of the patients and the BALF CDCs, as ...

Compositional data types

Proceedings of the seventh ACM SIGPLAN workshop on Generic programming, 2011
Building on Wouter Swierstra's Data types a la carte, we present a comprehensive Haskell library of compositional data types suitable for practical applications. In this framework, data types and functions on them can be defined in a modular fashion.

Data on Composition of Slovenian Food

2018 IEEE 34th International Conference on Data Engineering Workshops (ICDEW), 2018
Food composition databases comprise average values for nutrients and other components in food. Different environmental, agricultural and processing practices, as well as policies affect the contents of components in foods, which support the rationale for creation of national databases.

Robust Factor Analysis for Compositional Data [PDF]

open access: yesComputers and Geosciences, 2009
Factor analysis as a dimension reduction technique is widely used with compositional data. Using the method for raw data or for improperly transformed data will, however, lead to biased results and consequently to misleading interpretations. Although some procedures, suitable for factor analysis with compositional data, were already developed, they ...
