Overview of this book

In recent years, machine learning technologies and analytics have been widely utilized across the healthcare sector. Healthcare Analytics Made Simple bridges the gap between practising doctors and data scientists. It equips the data scientists’ work with healthcare data and allows them to gain better insight from this data in order to improve healthcare outcomes. This book is a complete overview of machine learning for healthcare analytics, briefly describing the current healthcare landscape, machine learning algorithms, and Python and SQL programming languages. The step-by-step instructions teach you how to obtain real healthcare data and perform descriptive, predictive, and prescriptive analytics using popular Python packages such as pandas and scikit-learn. The latest research results in disease detection and healthcare image analysis are reviewed. By the end of this book, you will understand how to use Python for healthcare data analysis, how to import, collect, clean, and refine data from electronic health record (EHR) surveys, and how to make predictive models with this data through real-world algorithms and code examples.

Preprocessing the predictor variables

Let's take a look at specific groups of predictor variables that commonly pop up in healthcare data.

Visit information

The first feature category in the ED2013 dataset contains information about the timing of the visit. Variables such as month, day of week, and arrival time are included here. Also included are the waiting time and length of visit variables (both in minutes).

Month

Let's analyze the VMONTH predictor in more detail. The following code prints all the values in the training set and their counts:
