Data Science for Marketing Analytics

By: Tommy Blanchard, Debasish Behera, Pranshu Bhatnagar

Overview of this book

Data Science for Marketing Analytics covers every stage of data analytics, from working with a raw dataset to segmenting a population and modeling different parts of the population based on the segments. The book starts by teaching you how to use Python libraries, such as pandas and Matplotlib, to read data from Python, manipulate it, and create plots, using both categorical and continuous variables. Then, you'll learn how to segment a population into groups and use different clustering techniques to evaluate customer segmentation. As you make your way through the chapters, you'll explore ways to evaluate and select the best segmentation approach, and go on to create a linear regression model on customer value data to predict lifetime value. In the concluding chapters, you'll gain an understanding of regression techniques and tools for evaluating regression models, and explore ways to predict customer choice using classification algorithms. Finally, you'll apply these techniques to create a churn model for modeling customer product choices. By the end of this book, you will be able to build your own marketing reporting and interactive dashboard solutions.

Preface

Decision Trees


Decision trees are mostly used for classification tasks. They are a non-parametric form of supervised learning method. Decision trees work on the concept of finding out the target variable by learning simple decision rules from data. They can be used for both classification and regression tasks. The following are the advantages and disadvantages of using decision tress for classification:

Advantages

  • Decision trees are very simple to understand and can be visualized.

  • They can handle both numeric and categorical data.

  • The requirement for data cleaning in the case of decision trees is very low since it is able to handle missing data.

  • It's a non-parametric machine learning algorithm that makes no assumption of space distribution and classifier structures.

  • It's a white box model rather than a black box model like neural networks, and is able to explain the logic of split using Boolean values.

Disadvantages

  • Decision trees tend to overfit data very easily, and pruning is required to...
