Transforming variables with the logarithm

The logarithm function is commonly used to transform variables. It has a strong effect on the shape of the variable distribution and can only be applied to positive variables. In this recipe, we will learn how to perform logarithmic transformation using NumPy, scikit-learn, and Feature-engine. We will also create a diagnostic plot function to evaluate the effect of the transformation on the variable distribution.

How to do it...

Let's begin by importing the libraries and classes we need and getting the dataset ready:

1. Import the required Python libraries, classes, and functions:

import numpy as np
import pandas as pd
import matplotlib.pyplot as plt
import scipy.stats as stats...
