## What is regression analysis and why is it important?

Regression analysis is a branch of statistics that deals with finding the relationship between a dependent variable (also called response or outcome) and one or more independent variables (also called predictors or explanatory). For example, you might want to study how the sales of a product depend on its price, advertising budget, quality, customer satisfaction, etc. Regression analysis can help you answer questions like:

How strong is the relationship between the variables?

What is the direction and shape of the relationship?

How well does the relationship fit the data?

How confident are we about the estimates of the relationship?

How can we use the relationship to make predictions or test hypotheses?

How can we improve the relationship by adding or removing variables or transforming them?

Regression analysis is widely used in many fields such as engineering, sociology, psychology, science, and business. It can help you understand complex phenomena, identify causal factors, optimize processes, evaluate policies, forecast trends, and make informed decisions.

## What are the main topics covered in the book?

The book covers various topics related to linear regression models and methods. Here are some of them:

### Simple linear regression

This chapter introduces the basic concepts and techniques of simple linear regression, which involves one dependent variable and one independent variable. You will learn how to:

Estimate the parameters of the regression equation using the method of least squares

Perform inference on the slope and intercept of the regression line using confidence intervals and hypothesis tests

Predict new values of the dependent variable using point estimates and prediction intervals

Check the adequacy of the regression model using residual analysis, coefficient of determination, standard error of estimate, etc.

### Multiple linear regression

This chapter extends the simple linear regression to multiple linear regression, which involves one dependent variable and two or more independent variables. You will learn how to:

Use matrix notation and operations to simplify the calculations and notation

Build multiple regression models using different methods such as all possible regressions, stepwise regression, backward elimination, etc.

Detect and deal with multicollinearity, which is the problem of high correlation among the independent variables

Perform model diagnostics using various tools such as residual plots, leverage, influence, outliers, etc.

### Nonlinear regression models

This chapter covers some nonlinear regression models that can better fit the data than linear models. You will learn how to:

Use polynomial models to capture the curvature or nonlinearity in the relationship

Use transformations to stabilize the variance or linearize the relationship

Use nonlinear least squares to estimate the parameters of nonlinear models

## What are the features and benefits of the book?

The book has many features and benefits that make it a valuable resource for learning regression analysis. Here are some of them:

The book uses real data and scenarios extracted from news articles, journals, and actual consulting problems to show how to apply the concepts and methods in practice.

The book includes seven case studies that invite you to focus on specific problems and are suitable for class discussion or group projects.

The book provides software support for various statistical packages such as SAS, SPSS, Minitab, Excel, etc. You will learn how to use these software to perform regression analysis and interpret the output.

The book offers many exercises and examples that help you test your understanding and reinforce your learning. The answers to odd-numbered exercises are given at the end of the book.

The book is written in a clear and concise style that makes it easy to follow and comprehend. The authors use a conversational tone and utilize personal pronouns, rhetorical questions, analogies, and metaphors to engage the reader.
