Hands-On Exploratory Data Analysis with Python

By: Suresh Kumar Mukhiya, Usman Ahmed

Overview of this book

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.

Time Series Analysis

Time series data includes timestamps and is often generated while monitoring the industrial process or tracking any business metrics. An ordered sequence of timestamp values at equally spaced intervals is referred to as a time series. Analysis of such a time series is used in many applications such as sales forecasting, utility studies, budget analysis, economic forecasting, inventory studies, and so on. There are a plethora of methods that can be used to model and forecast time series.

In this chapter, we are going to explore Time Series Analysis (TSA) using Python libraries. Time series data is in the form of a sequence of quantitative observations about a system or process and is made at successive points in time.

In this chapter, we are going to cover the following topics:

  • Understanding time series datasets
  • TSA with Open Power System Data
