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.

Performance Metrics


In the case of classification algorithms, we use a confusion matrix, which gives us the performance of the learning algorithm. It is a square matrix that counts the number of true positive (TP), true negative (TN), false positive (FP), and false negative (FN) outcomes.

Figure 8.48: Confusion matrix

True positive: The number of cases that were observed and predicted as 1.

False negative: The number of cases that were observed as 1 but predicted as 0.

False positive: The number of cases that were observed as 0 but predicted as 1.

True negative: The number of cases that were observed as 1 but predicted as 0.

Precision

It is the ability of a classifier to not label a sample that is negative as positive. The precision for an algorithm is calculated using the following formula:

This is useful in the case of email spam detection. In this scenario, we do not want any important emails to be detected as spam.

Recall

It refers to the ability of a classifier to...
