Exploratory factor analysis. The Multivariate Normal Distribution 3.1 Introduction • A generalization of the familiar bell shaped normal density to several dimensions plays a fundamental role in multivariate analysis • While real data are never exactly multivariate normal, the normal density is often a useful approximation to the “true” population distribution because of a central limit effect. 17.
