TY - JOUR AU - Jackson, J. Edward AB - Principal components and factor analysis are two techniques which are finding increasing application to quality engineers who are concerned with processes with more than one response variable. In this, the first of a three-part series, the concept of principal components is introduced. Estimations, significance tests, and residual analysis are presented along with two numerical examples. Parts two and three will be found in succeeding issues.
