Statistical Application Development with R and Python - Second Edition

Overview of this book

Statistical Analysis involves collecting and examining data to describe the nature of data that needs to be analyzed. It helps you explore the relation of data and build models to make better decisions. This book explores statistical concepts along with R and Python, which are well integrated from the word go. Almost every concept has an R code going with it which exemplifies the strength of R and applications. The R code and programs have been further strengthened with equivalent Python programs. Thus, you will first understand the data characteristics, descriptive statistics and the exploratory attitude, which will give you firm footing of data analysis. Statistical inference will complete the technical footing of statistical methods. Regression, linear, logistic modeling, and CART, builds the essential toolkit. This will help you complete complex problems in the real world. You will begin with a brief understanding of the nature of data and end with modern and advanced statistical models like CART. Every step is taken with DATA and R code, and further enhanced by Python. The data analysis journey begins with exploratory analysis, which is more than simple, descriptive, data summaries. You will then apply linear regression modeling, and end with logistic regression, CART, and spatial statistics. By the end of this book you will be able to apply your statistical learning in major domains at work or in your projects.

Chapter 3. Data Visualization

Data is possibly best understood, wherever plausible, if it is displayed in a reasonable manner. Chen et. al. (2008) have compiled articles where many scientists of data visualization give a deeper, historical and modern trend of data display. Data visualization may be as historical as data itself. It emerges across all the dimensions of science, history, and every stream of life where data is captured. The reader may especially go through the rich history of data visualization in the article of Friendly (2008) from Chen et. al. (2008). The aesthetics of visualization have been described elegantly in Tufte (2001). The current chapter will have a deep impact on the rest of the book, and this chapter aims to provide the guidance and specialized graphics in the appropriate context in the rest of the book.

This chapter provides the necessary stimulus for understanding the gist that discrete and continuous data need appropriate tools, and that validation may be seen...
