An introduction to multivariate data analysis - Trevor Cox

Multivariate data appear in all scientific fields of investigation and the study of multivariate analysis has become central to the discipline of data science. Not only is it part of the statistical education curriculum but it is also an essential tool for applied scientists in their research work. An Introduction to Multivariate Data Analysis clearly explains how to successfully reduce a large and complex set of data with many variables to a manageable new formulation where information, structure and underlying patterns are more clearly revealed.
