Linear Regression in Python - Full Project for Beginners
Welcome to this comprehensive "Linear Regression with Python Tutorial" for beginners! In this video, we will cover the basics of linear regression, a fundamental concept in data science and machine learning. With this tutorial, you will learn how to perform data analysis using linear regression in Python. This tutorial is perfect for anyone who is new to the field of data science and machine learning and wants to get started with a real-world data science project.
We will start by introducing the concepts of statistical learning and statistics, and then move on to applying these concepts in Python to perform linear regression. You will learn how to use Python libraries such as NumPy and Pandas for data preprocessing, and then use scikit-learn for building and evaluating a linear regression model.
By the end of this tutorial, you will have a solid understanding of linear regression and how to apply it in Python for your own data science projects. So, if you're ready to dive into the world of data science and machine learning, make sure to watch this tutorial till the end. Don't forget to like and subscribe for more tutorials like this!

This is really awesome, it helped me to understand linear regression concept , love the way you teach through projects.
After watching a lot of videos for Linear Regression your video is by far THE BEST!!! thanks. Just one thing couldn't use scatterplot got a 'scatterplot() takes from 0 to 1 positional arguments but 2 were given' error.
Amazing! Please keep doing these beginner friendly projects, theyre incredibly useful
It is very helpful. Keep up with the great work!
You are great brother.
Great video! Here's a quick tip: consider using distplot to display Yhat and Y_test in the same axis to evaluate your model's performance.
very helpful, thank you
Thank you for this lesson, Alejandro: it helped me tremendously. Have a nice day and great holidays.

thank you!!
I have watched endless Regression videos. I graduated with a math degree a couple years ago, and my programming skills are beginner level. I've done Datacamp stuff, youtube guided projects, you name it. This is by far the most concise, easy to follow, welcoming, calming video I have ever watched explaining how to do a regression project. I appreciate the quick definitions along the way, that help the audience including myself, not feel stupid lol. And explaining every small step really helps. Also the big picture explanation of how leverage this code and automate it, was helpful. Very few if any, ever talks about that step. I'm trying to get crack into the tech world and land a data job. Just this one video has truly given me the confidence, to not feel overwhelmed and that its obtainable. Sorry for the lengthy response haha Please keep making videos man, you rock!!

So wholesome! Thanks for helping me find the best video.
looking forward to another END TO END video but for more intermediate level!
I'm a math major with a minor in CS. I'm looking to break into data science. Your video was very informative and easy to follow. Thank you!

hey there! it makes me very happy to hear that! keep it up ;)
Wonderful video! I was able to follow along happily until the scatterplot command, for which I got the error, "TypeError: scatterplot() takes from 0 to 1 positional arguments but 2 were given". Had to change the command to sns.scatterplot(x=predictions, y=y_test). Everything else was perfect, and I learned a lot - THANK YOU!!!

Hey. Nice video. There's just a thing I'm not sure about. Shouldn't normality, homoscedasticity and tests regarding residuals be done over y_train - predict, where predict is based on the training set? You verified the normality assumption on residuals of y_test - "predict_test". Which one is it?
It is very helpful brother, Keep up good work!

The coefficient does not determine the most important. The magnitude of each variable varies in the formula. A small coefficient applied to a variable with more magnitude can be the most variance on the model
Can you tell me from where I can get this csv file ?
