This Linear Regression Algorithm video is designed in a way that you learn about the algorithm in depth. This video is designed in a way that in the first part you will learn about the algorithm from scratch with its mathematical implementation, then you will drill down to the coding part and implement linear regression using python. Below are the topics covered in this tutorial:
1. What is Regression?
2. Regression Use-case
3. Types of Regression - Linear vs Logistic Regression
4. What is Linear Regression?
5. Finding best-fit regression line using Least Square Method
6. Checking goodness of fit using R squared Method
7. Implementation of Linear Regression Algorithm using Python (from scratch)

Why learn Machine Learning with Python?
Data Science is a set of techniques that enable the computers to learn the desired behavior from data without explicitly being programmed. It employs techniques and theories drawn from many fields within the broad areas of mathematics, statistics, information science, and computer science. This course exposes you to different classes of machine learning algorithms like supervised, unsupervised and reinforcement algorithms. This course imparts you the necessary skills like data pre-processing, dimensional reduction, model evaluation and also exposes you to different machine learning algorithms like regression, clustering, decision trees, random forest, Naive Bayes and Q-Learning.

Where is the dataset?
For Stock Price predictor can day be Independent variable and Price be Dependent variable. Is Linear regression fit for Stock Market Price predictors??
The main difference between them is that the output variable in regression is numerical (or continuous) while that for classification is categorical (or discrete). However, they both are categorized under the same umbrella of supervised machine learning.
If the goal is prediction or forecasting or error reduction, linear regression can be used to fit a predictive model to an observed data set of y and x values.
The explanation was top-notch, Kudos to the instructor and specially Edureka for making this, Thank You.

24:20 - Programming part
You guys have a video on literallyy every topic, don't ya🔥❤️😂
You are a world-class instructor, your speaking skills are really good. Even I had completed the video in 2x speed, I did not find any place where I have to replay the part. The linear regression algorithm is explained in the easiest possible way. Thanks for the effort!!!!
the perfect explanation of linear regersssion model
Thank You 😊 Glad it was helpful!!! Keep learning with us..
best video i have ever seen on linear regression

thank you so much for making my life easy............ i am M.Tech(AI) student struggling with linear regression from yesterday
The only video that helped me in calculating the best fit line in so much detail and plain english. Thanks for the same.
really a great work.kindly explain the code slowly
A great video with all explanations about the model 👍 Could you please explain why one was subtracted while calculating r squared value
watched lots of videos to learn this. understood nothing. but, u guys just killed it.

Awesome explanation . Thank you edureka. Explanation is Very understandable manner to even poor mathematical background people. I need clarification. When R(square) is very less how to increase R(square) to make best fit of line. Is there any formula or mathematical procedure. Kindly clarify me.
Hi Ravi, thanks for the compliment. Try removing any insignificant variables. Usually when there are more predictor variables in the data set, the R square value tends to decrease.
This explanation was so clear, even a man who dont know about machine learning , the person can easily understand the concept.

The best explanation i have seen on this topic. Thank you.
Wow, thanks!
Simply Wounderful
Thank You 😊 Glad it was helpful!
Very Good , looking for Mathematical understanding for prediction and code implementation. Very Much satisfied to understand prediction derivation. Thanks much.
Need help
what if the coordinates are not continuous on the x axis
for example
x-axis = 0 1 2 3 4 5
y-axis = 0 1 2 3 4 5
coordinates = (2,3) (4,3)
there is a gap between the x coordinates
so is it possible to get the regression line ?
Best explaination I have ever seen for linear regression the visual explaination, mathematical theory awesome video please keep posting.

Hello team,
Should we need to convert all continuous independent variables to categorical variables for logistic regression?
Nice , well explained.
Excellent explanation and so far the best video i have seen.
it will be very helpful if you share the ppts too
Great stuff!!Please send in the dataset
My Question is there, I have seen lots of videos on youtube but i didn't get way how to use machince learning in real life..
Hi Vikas, You can check out our Machine Learning playlist.
We have explained Machine Learning with the help of real world example and projects.
