Factor Analysis Professor Schepers’ book is designed to introduce postgraduate students to the fundamentals of factor analysis, which provides the groundwork for a deep understanding of the technique. Emphasising the centroid method, Professor Schepers demonstrates how factor analysis is done - right through the factor extraction and rotation process - which the serious student can follow and repeat step by step. His book will provide them with a solid understanding of what actually happens when they press the Analyse button on their computer keyboards.
