The Multivariate analysis module is useful for exploratory analysis of multivariate quantitative data. Further, it allows you to perform the principal components analysis. Multivariate data (formally a random sample with vector-valued observations) arise as a result of simultaneous measurement of several (m) variables on the same unit. For instance, several physical and/or chemical properties of one sample can be measured, several linear measurements can be taken on the same piece of product, or there might be several characteristics for any employee available.
