Overview of this book

This book leverages the author’s decade-long experience in biostatistics and data science to simplify the practical use of biostatistics with Python. The chapters show you how to clean and describe your data effectively, setting a solid foundation for accurate analysis and proficiency in biostatistical inference to help you draw meaningful conclusions from your data through hypothesis testing and effect size analysis. The book walks you through predictive modeling to harness the power of Python to create robust predictive analytics that can drive your research and professional projects forward. You'll explore clinical biostatistics, learn how to design studies, conduct survival analysis, and synthesize evidence from multiple studies with meta-analysis – skills that are crucial for making informed decisions based on comprehensive data reviews. The concluding chapters will enhance your ability to analyze biological variables, enabling you to perform detailed and accurate data analysis for biological research. This book's unique blend of biostatistics and Python helps you find practical solutions that make complex concepts easy to grasp and apply. By the end of this biostatistics book, you’ll have moved from theoretical knowledge to practical experience, allowing you to perform biostatistical analysis confidently and accurately.

Cleaning missing values and invalid data

By default, the pandas read_csv() function will read a variable as if it’s non-numeric (string) if it contains at least one string (text). So, what’s the difference between nan instances in the Petal_width column and the Sepal_width column? Python will convert empty cells into nan values but will keep the numeric nature of the variable, as is the case for the Petal_length variable.

In biostatistics, experimenters might use different words to mark a missing value, such as Nan or NA (short for not applicable), or even whole words such as missing or not applicable. Remember that Nan and NA are still strings, so if there’s an empty cell, Python will read it as a string and coerce the whole variable into a string variable. This wasn’t the case for Petal_width since Python read empty cells as nan and didn’t coerce the variable into a string, instead keeping it numeric. In this case, Python read nan as the valid...
