Multivariate Linear Models
Chapters 1, 2, and 3 examine topics in multivariate analysis. Specifically, they discuss multivariate linear models, discriminant analysis, principal components, and factor analysis. The basic ideas behind these subjects are closely related to linear model theory. Multivariate linear models are simply linear models with more than one dependent variable. Discriminant analysis is closely related to both Mahalanobis’s distance (see Christensen, 1996a, Section 13.1) and multivariate one-way analysis of variance. Principal components are user-constructed variables which are best linear predictors (see Christensen, 1996a, Section 6.3) of the original data. Factor analysis has ties to both multivariate linear models and principal components.
