Mastering Python Data Analysis

By: Magnus Vilhelm Persson

Overview of this book

Python, a multi-paradigm programming language, has become the language of choice for data scientists for data analysis, visualization, and machine learning. Ever imagined how to become an expert at effectively approaching data analysis problems, solving them, and extracting all of the available information from your data? Well, look no further, this is the book you want! Through this comprehensive guide, you will explore data and present results and conclusions from statistical analysis in a meaningful way. You’ll be able to quickly and accurately perform the hands-on sorting, reduction, and subsequent analysis, and fully appreciate how data analysis methods can support business decision-making. You’ll start off by learning about the tools available for data analysis in Python and will then explore the statistical models that are used to identify patterns in data. Gradually, you’ll move on to review statistical inference using Python, Pandas, and SciPy. After that, we’ll focus on performing regression using computational tools and you’ll get to understand the problem of identifying clusters in data in an algorithmic way. Finally, we delve into advanced techniques to quantify cause and effect using Bayesian methods and you’ll discover how to use Python’s tools for supervised machine learning.

Preface

Summary


In this chapter, we looked at the many and interesting aspects of time series analysis in Python with Pandas and statsmodels, how they handle the data, and some of the basic manipulation functions that are available. We also looked at the concept of stationarity, how to test your time series for it, and how to transform a non-stationary series into a stationary one. You also found out the various patterns and components that time series can be built up by, and finally, we went through how to create ARIMA models and predict future values based on previous historical data.

This chapter concludes the book. We have covered many different analysis techniques and general statistical knowledge and how to use them in Python to your benefit. With the knowledge in this book, you can start exploring data, any kind of data. In addition to these chapters, there is an appendix. In Appendix, More on Jupyter Notebook and matplotlib Styles, I will look at Jupyter Notebook tips and extensions (plugins...
