Mathematical procedure that transforms a number of possibly correlated variables into a smaller number of uncorrelated variables called principal components. (NALT https://lod.nal.usda.gov/nalt/59637)
Note
A statistical method for reducing the dimensionality of a set of multivariate observations. Each principal component is a specific linear combination of the original variables such that all principal components account for a smaller proportion of the original variation.
