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

U.S. air travel safety record


In this example, we will look at a dataset from the U.S. National Transportation Safety Board (NTSB). The NTSB has an open database that can be downloaded from their web page,  http://www.ntsb.gov . One important thing about the data is that it contains civil aviation accidents and selected incidents within the United States, its territories and possessions, and in international waters, that is, it is not for the whole world. Basically, it is for U.S.-related accidents only, which makes sense for a U.S. national organization. There are databases that contain the whole world, but with less fields in them. For example, the NTSB dataset contains information about minor injuries for the accident in question. For comparison, and as an opening for exercises, after the Bayesian analysis of the NTSB data, we shall load and have a quick look at a dataset from OpenData by Socrata ( https://opendata.socrata.com ) that covers the whole world. The question that we want to...
