One method for doing this is to use Huber's influence function, which is illustrated ... of the residual (usually denoted by r, which is arbitrarily set to 1 in this plot), beyond which all observations will have the same influence.
Intuitively understand regression analysis by focusing on concepts and graphs rather than equations and formulas.
Completing this book will allow you to understand and build basic business/economic models using regression analysis.
This book provides an efficient alternative approach, with more time devoted to the practical aspects of regression analysis and how to recognize the most common pitfalls.
Consequently, this book provides a sound foundation in the theory of this important subject.
The book provides a non-theoretical treatment that is accessible to readers with even a limited statistical background. This book describes exactly how regression models are developed and evaluated.
Consequently, this book provides a sound foundation in the theory of this important subject.
Regression Analysis: Concepts and Applications focuses on thinking clearly about and solving practical statistical problems.
Regression Analysis: Modeling & Forecasting
This book describes exactly how regression models are developed and evaluated. Real data are used, instead of contrived textbook-like problems. The data used in the book are the kind of data managers are faced with in the real world.
This is made possible through an efficient, integrative discussion of the two techniques.
