To access the constant term in the linear regression equation, you can use theintercept_attribute of the linear regression model. The entire program to implement simple linear regression using the sklearn module in Python is as follows. from sklearn.linear_model import LinearRegression import numpy...
Additional Regression Problems. Apply the technique to other regression problems on the UCI machine learning repository. Did you explore any of these extensions? Let me know about it in the comments below. Review In this tutorial, you discovered how to implement linear regression using stochastic gr...

where the i refers to the value of the ith value of the input x or output y. Don’t worry if this is not clear right now, these are the functions will implement in the tutorial. Swedish Insurance Dataset We will use a real dataset to demonstrate simple linear regression. The dataset ...
Explore Program Installation and Configuration How to Install Scikit-learn? As we have already seen in the prerequisites section, there is a whole set of other tools and libraries that we need to install before diving into the installation of Scikit-learn. So, let’s start off by discussing...
You’ll learn how to create datasets, split them into training and test subsets, and use them for linear regression. As always, you’ll start by importing the necessary packages, functions, or classes. You’ll need NumPy, LinearRegression, and train_test_split(): Python >>> import numpy...
In this quiz, you'll test your understanding of Python's dunder repr and dunder str special methods. These methods allow you to control how a program displays an object, making your classes more readable and easier to debug and maintain. ...
