Mastering pandas - Second Edition

By: Ashish Kumar

Overview of this book

pandas is a popular Python library used by data scientists and analysts worldwide to manipulate and analyze their data. This book presents useful data manipulation techniques in pandas to perform complex data analysis in various domains. An update to our highly successful previous edition with new features, examples, updated code, and more, this book is an in-depth guide to get the most out of pandas for data analysis. Designed for both intermediate users as well as seasoned practitioners, you will learn advanced data manipulation techniques, such as multi-indexing, modifying data structures, and sampling your data, which allow for powerful analysis and help you gain accurate insights from it. With the help of this book, you will apply pandas to different domains, such as Bayesian statistics, predictive analytics, and time series analysis using an example-based approach. And not just that; you will also learn how to prepare powerful, interactive business reports in pandas using the Jupyter notebook. By the end of this book, you will learn how to perform efficient data analysis using pandas on complex data, and become an expert data analyst or data scientist in the process.

Summary

In this chapter, we undertook a whirlwind tour of one of the hottest trends in statistics and data analysis in the past few years—the Bayesian approach to statistical inference. We covered a lot of ground here.

We examined what the Bayesian approach to statistics entails and discussed the various reasons why the Bayesian view is a compelling one, such as the fact that it values facts over belief. We explained the key statistical distributions and showed how we can use the various statistical packages to generate and plot them in matplotlib.

We tackled a rather difficult topic without too much oversimplification and demonstrated how we can use the PyMC package and Monte Carlo simulation methods to showcase the power of Bayesian statistics to formulate models, perform trend analysis, and make inferences on a real-world dataset (Facebook user posts). The concept of...
