Online Workshop: introduction to compositional data analysis
Online Workshop: introduction to compositional data analysis
Tolosana Delgado, R.; Pospiech, S.
Abstract
In this 2-day webinar we will see the problems arising with the conventional statistical analysis of compositional data, and present a general solution. We will learn how to generate and interpret compositional descriptive statistics; how to explore the inner structure of a data set with tools such as logratio principal component analysis; and we will fit predictive models to explain the variability in compositional data sets. These topics will be covered with a bit of theory, some examples from geochemistry and a few exercises in R, the open source environment for data analysis.
Keywords: PCA; alr; clr; regression; compositional data analysis; geochemistry
