Preface to Multiple Regression and Beyond 3rd Edition

Multiple Regression and Beyond is designed to provide a conceptually oriented introduction to multiple regression along with more complex methods that flow naturally from multiple regression: path analysis, confirmatory factor analysis, and structural equation modeling.

Multiple regression (MR) and related methods have become indispensable tools for modern social science researchers.

MR closely implements the general linear model and thus subsumes methods, such as analysis of variance (ANOVA), that have traditionally been more commonplace in psychological and educational research.

Regression is especially appropriate for the analysis of nonexperimental research, and with the use of dummy variables and modern computer packages, it is often more appropriate or easier to use MR to analyze the results of complex quasi-experimental or even experimental research.

Extensions of multiple regression—particularly structural equation modeling (SEM)—partially obviate threats due to the unreliability of the variables used in research and allow the modeling of complex relations among variables.

A quick perusal of the full range of social science journals demonstrates the wide applicability of the methods. Despite its importance, MR-based analyses are too often poorly conducted and poorly reported.

I believe one reason for this incongruity is inconsistency between how material is presented and how most students best learn. Anyone who teaches (or has ever taken) courses in statistics and research methodology knows that many students, even those who may become gifted researchers, do not always gain conceptual understanding only through numerical presentation.

Although many who teach statistics understand the processes underlying a sequence of formulas and gain conceptual understanding through these formulas, many students do not.

Instead, such students often need a thorough conceptual explanation to gain such understanding, after which a numerical presentation may make more sense. Unfortunately, many multiple regression textbooks assume that students will understand multiple regression best by learning matrix algebra, wading through formulas, and focusing on details.

At the same time, methods such as structural equation modeling (SEM) and confirmatory factor analysis (CFA) are easily taught as extensions of multiple regression.

If structured properly, multiple regression flows naturally into these more complex topics, with nearly complete carry-over of concepts.

Path models (simple SEMs) illustrate and help deal with some of the problems of MR, CFA does the same for path analysis, and latent variable SEM combines all the previous topics into a powerful, flexible methodology.

I have taught courses including these topics at four universities (the University of Iowa, Virginia Polytechnic Institute & State University, Alfred University, and the University of Texas).

These courses included students and faculty in architecture, engineering, educational psychology, educational research and statistics, kinesiology, management, political science, psychology, social work, and sociology, among others.

This experience leads me to believe that it is possible to teach these methods by focusing on the concepts and purposes of MR and related methods, rather than the derivation and calculation of formulas.

Nonquantitatively-oriented students generally find such an approach clearer, more conceptual, and less threatening than other approaches.

As a result of this conceptual approach, students become interested in conducting research using MR, CFA, or SEM and are more likely to use the methods wisely
