商品描述

This book presents the statistical analysis of compositional data using the log-ratio approach. It includes a wide range of classical and robust statistical methods adapted for compositional data analysis, such as supervised and unsupervised methods like PCA, correlation analysis, classification and regression. In addition, it considers special data structures like high-dimensional compositions and compositional tables. The methodology introduced is also frequently compared to methods which ignore the specific nature of compositional data. It focuses on practical aspects of compositional data analysis rather than on detailed theoretical derivations, thus issues like graphical visualization and preprocessing (treatment of missing values, zeros, outliers and similar artifacts) form an important part of the book. Since it is primarily intended for researchers and students from applied fields like geochemistry, chemometrics, biology and natural sciences, economics, and social sciences, all the proposed methods are accompanied by worked-out examples in R using the package robCompositions.

商品描述(中文翻譯)

本書介紹了使用對數比率方法進行組成數據的統計分析。它涵蓋了一系列經典和穩健的統計方法,這些方法已針對組成數據分析進行調整,包括監督式和非監督式方法,如主成分分析(PCA)、相關分析、分類和回歸。此外,它還考慮了特殊數據結構,如高維組成和組成表。所介紹的方法論也經常與忽略組成數據特定性質的方法進行比較。本書重點關注組成數據分析的實際方面,而非詳細的理論推導,因此圖形可視化和預處理(缺失值、零值、異常值及類似工件的處理)等問題構成了本書的重要部分。由於本書主要針對來自應用領域的研究人員和學生,如地球化學、化學計量學、生物學和自然科學、經濟學及社會科學,因此所有提出的方法均附有使用 robCompositions 套件在 R 語言中的實作範例。
