Overview of this book

R provides excellent visualization features that are essential for exploring data before using it in automated learning. Applied Supervised Learning with R helps you cover the complete process of employing R to develop applications using supervised machine learning algorithms for your business needs. The book starts by helping you develop your analytical thinking to create a problem statement using business inputs and domain research. You will then learn different evaluation metrics that compare various algorithms, and later progress to using these metrics to select the best algorithm for your problem. After finalizing the algorithm you want to use, you will study the hyperparameter optimization technique to fine-tune your set of optimal parameters. The book demonstrates how you can add different regularization terms to avoid overfitting your model. By the end of this book, you will have gained the advanced skills you need for modeling a supervised machine learning algorithm that precisely fulfills your business needs.

Preface

Bivariate Analysis


In bivariate analysis, we extend our analysis to study two variables together. In our use case, we have around 20 independent variables. It is indeed possible to study all permutation combinations of the available 20 variables, but we won't go to that extent in this chapter. In our use case, we are more interested in studying all the factors that led to the poor performance of the campaign. Therefore, our primary focus will be to perform bivariate analysis and study the relationship between all the independent variables and our dependent target variable. Again, depending on the type of variable, we will have a different type of visual or analytical technique to analyze the relationship between the two variables. The possible combinations are numeric and numeric, and numeric and categorical. Given that our dependent variable is a categorical variable, we might have to explore the relationship between two independent variables in our list to study the relationship between...
