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.

A Linux user may simply key in sudo apt-get install r-base in the Terminal, and post the return of the right password and privilege levels, and the R software would be installed. After the completion of the download and installation, the software is started by simply keying in R in the Terminal.

A Windows user needs to perform the following steps:

  1. Firstly, click on Download R for Windows, as shown in the preceding screenshot.

  2. Then in the base subdirectory click on install R for the first time.

  3. In the new window, click on Download R 3.4.0 for Windows and download the .exe file to a directory of your choice.

  4. The completely downloaded R-3.0.0-win.exe file can be installed as any other .exe file.

  5. The R software may be invoked either from the Start menu, or from the icon on the desktop. The installed versions of R in Windows and Linux appears as follows:
