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.

Summary


We have discussed how to test models and hypotheses with Bayesian analysis using the Python package, PyMC. It is a powerful package that gives out more intuitive results, where you see how the parameters are characterized. Not all posterior distributions are shaped like Gaussian, but the trace and autocorrelation should look similar for well-constrained parameters.

In the next chapter, we will dive into some of the machine learning algorithms available in Python and look at how they can identify clusters, classify data, and do linear regression. As in this chapter, we will compare the linear fit with that of Bayesian analysis and OLS. We will compare the cluster findings with the analysis that we did of galaxies in the universe in Chapter 5 , Clustering .
