Multivariate methods
Use multivariate analyses to evaluate relationships among variables from many
different perspectives. Perform multivariate tests of means, or fit
multivariate regression and MANOVA models. Explore relationships between two
sets of variables, such as aptitude measurements and achievement measurements,
using canonical correlation. Examine the number and structure of latent
concepts underlying a set of variables using exploratory factor analysis. Or
use principal component analysis to find underlying structure or to reduce the
number of variables used in a subsequent analysis. Discover groupings of
observations in your data using cluster analysis. If you have known groups in
your data, describe differences between them using discriminant analysis. And
much more.
