Book Description

Exploratory Data Analysis (EDA) is an approach to data analysis that involves the application of diverse techniques to gain insights into a dataset. This book will help you gain practical knowledge of the main pillars of EDA - data cleaning, data preparation, data exploration, and data visualization.

You’ll start by performing EDA using open source datasets and perform simple to advanced analyses to turn data into meaningful insights. You’ll then learn various descriptive statistical techniques to describe the basic characteristics of data and progress to performing EDA on time-series data. As you advance, you’ll learn how to implement EDA techniques for model development and evaluation and build predictive models to visualize results. Using Python for data analysis, you’ll work with real-world datasets, understand data, summarize its characteristics, and visualize it for business intelligence.

By the end of this EDA book, you’ll have developed the skills required to carry out a preliminary investigation on any dataset, yield insights into data, present your results with visual aids, and build a model that correctly predicts future outcomes.

What you will learn
  • Import, clean, and explore data to perform preliminary analysis using powerful Python packages
  • Identify and transform erroneous data using different data wrangling techniques
  • Explore the use of multiple regression to describe non-linear relationships
  • Discover hypothesis testing and explore techniques of time-series analysis
  • Understand and interpret results obtained from graphical analysis
  • Build, train, and optimize predictive models to estimate results
  • Perform complex EDA techniques on open source datasets
Who this book is for

This EDA book is for anyone interested in data analysis, especially students, statisticians, data analysts, and data scientists. The practical concepts presented in this book can be applied in various disciplines to enhance decision-making processes with data analysis and synthesis. Fundamental knowledge of Python programming and statistical concepts is all you need to get started with this book.

Brukerevaluering - Merk som upassende

One of the positive point, being a beginner programmer and student in data science, it gives a lot of examples and tricks that you need to know about EDA. Indeed, it was useful to for me to understand the basic to advance concept. However, more examples on theory would have been much better.
