Jolliffe I. Principal Component Analysis (2ed., Springer, 2002)(518s)

1.2. A Brief History of Principal Component Analysis 9Despite the apparent simplicity of the technique, much research is stillbeing done in the general area of PCA, and it is very widely used. This isclearly illustrated by the fact that the Web of Science identifies over 2000articles published in the two years 1999–2000 that include the phrases ‘principalcomponent analysis’ or ‘principal components analysis’ in their titles,abstracts or keywords. The references in this book also demonstrate thewide variety of areas in which PCA has been applied. Books or articlesare cited that include applications in agriculture, biology, chemistry, climatology,demography, ecology, economics, food research, genetics, geology,meteorology, oceanography, psychology and quality control, and it wouldbe easy to add further to this list.
