Principal component analysis (PCA) is a technique that is useful for the compression and classification of data. The purpose is to reduce the dimensionality of a data set (sample) by finding a new set of variables, smaller than the original set of variables, that nonetheless retains most of the sample's information. By information we mean the variation present in the sample, given by the jection of the original vectors on to qdirections, the principal components, which span the sub-space. There are several equivalent ways of deriving the principal components math-
