Multivariate analysis is the statistical analysis of several variables at once. This is when multiple measurements are made on each experimental unit, and for which the relationship among multivariate measurements and their structure are important to the experiment's understanding. Experimental units are what you apply the treatments to. Many problems in the analysis of life science are multivariate in nature. However the analysis of large multivariable data sets is a major challenge for many research fields. Applications of multivariate techniques are vast. Some includes behavioral and biological sciences, finance, geophysics, medicine, ecology, and many other fields. The materials in this chapter will form the basis of discussion for what will be discussed later in this text.
