1.6.1Principal component analysis Principal componentanalysis (PCA) is a dimensionality reduction method used to project data to a lower-dimensional space. PCA is widely used in planetary science—for example, Chapter8uses PCA for exploratorydata analysis ofhyperspectral imageobservations of Saturn from...
This article considers critically how one of the oldest and most widely applied statistical methods, principal components analysis (PCA), is employed with spatial data. We first provide a brief guide to how PCA works: This includes robust and compositional PCA variants, links to factor analysis, ...

Principal component analysis (PCA) is a widely used dimension reduction tool in high-dimensional data analysis. In risk quantification in finance, climatology and many other applications, however, the interest lies in capturing the tail variations rather than variation around the mean. To this end,...

3.5Beta diversity analysis The closer the two samples in the principal component analysis (PCA) graph and principal coordinates analysis (PCoA) graph, the more similar the species composition of the two samples. The R language was used to draw the PCA graph (Fig. 8) and the PCoA graph (Fig...
