Handling other issues in linear regression

So far in this chapter, we have learnt:

• How to implement a linear regression model using two methods
• How to measure the efficiency of the model using model parameters

However, there are other issues that need to be taken care of while dealing with data sources of different types. Let's go through them one by one. We will be using a different (simulated) dataset to illustrate these issues. Let's import it and have a look at it:

import pandas as pd
df=pd.read_csv('E:/Personal/Learning/Predictive Modeling Book/Book Datasets/Linear Regression/Ecom Expense.csv')
df.head()

We should get the following output:
