Applying Math with Python - Second Edition

By: Sam Morley

Overview of this book

The updated edition of Applying Math with Python will help you solve complex problems in a wide variety of mathematical fields in simple and efficient ways. Old recipes have been revised for new libraries and several recipes have been added to demonstrate new tools such as JAX. You'll start by refreshing your knowledge of several core mathematical fields and learn about packages covered in Python's scientific stack, including NumPy, SciPy, and Matplotlib. As you progress, you'll gradually get to grips with more advanced topics of calculus, probability, and networks (graph theory). Once you’ve developed a solid base in these topics, you’ll have the confidence to set out on math adventures with Python as you explore Python's applications in data science and statistics, forecasting, geometry, and optimization. The final chapters will take you through a collection of miscellaneous problems, including working with specific data formats and accelerating code. By the end of this book, you'll have an arsenal of practical coding solutions that can be used and modified to solve a wide range of practical problems in computational mathematics and data science.

Using multilinear regression

Simple linear regression, as seen in the previous recipe, is excellent for producing simple models of a relationship between one response variable and one predictor variable. Unfortunately, it is far more common to have a single response variable that depends on many predictor variables. Moreover, we might not know which variables from a collection make good predictor variables. For this task, we need multilinear regression.

In this recipe, we will learn how to use multilinear regression to explore the relationship between a response variable and several predictor variables.

Getting ready

For this recipe, we will need the NumPy package imported as np, the Matplotlib pyplot module imported as plt, the Pandas package imported as pd, and an instance of the NumPy default random number generator created using the following commands:

from numpy.random import default_rng
rng = default_rng(12345)

We will also need the statsmodels.api module imported...
