Multiple Linear Regression using R ( All about it )

Regression is a popular predictive algorithm especially for numerical continuous variables. In this video, we will see how to create a regression model and analyse the results using R step by step.
R Program installation steps:-
Please install R framework in your system. It is available for Linux,Windows and Mac systems below.

Also, after you install R framework, install the IDE(Integrated Development Environment), i.e R studio Desktop from below link.

Such a great and clear video! I watched so many videos but couldn't find something which clearly explains linear and multiple regression on R so clearly. Thanks a lot!

Thanks for the explanation, it was really helpful ☺️

Thank you very much! You helped me so much

Thank for the video. Can we find whether the error is homoskedastic using your table with coefficients? if the standard deviations for two variables are close to each other?

thank u for this. how would you plot the regressed variable recommendation coded in 0 and 1, and other variables in values ranging from 1-16????

[@dataexplained7305]

Looks like you need to do categorization by probability of occurrence. This should follow the regression analysis..

[@ahmed007Jaber]

@@dataexplained7305 would you be able to explain how this would be done? appreciate your feedback

[@dataexplained7305]

Sorry for delay.. I haven't done this myself.. can check and make a video soon..

how can I prove that Residual standard error is equal to the square root of MSE? can i find this information using the linear regression?

[@dataexplained7305]

Calculate the error( i.e., PredictedY-ActualY) -> square that difference for each row -> then get the Mean of that whole column -> Square root of it. This will give you the Root Mean Square Error. When you stop before making the square root, it will give you the Mean Square Error. Now, you can show this in the script by using two functions RMSE(y_pred, y_true) and MSE(y_pred, y_true). Hope this helps !! Let me know

Thank you so much!!!

Well Explained, simplified... but am having a doubt is this multiple regression or curvilinear regression.. Can you clear my doubt..

Sorry missed this... whats your doubt ?

Hi. Is there any way to perform multiple linear regression on raster time series images?

[@dataexplained7305]

Looks yes to me but haven't done it myself TBH..

[@nad1165]

Can we find the R skript of the codes somewhere? Btw: Very good video

[@dataexplained7305]

Thanks.. you might have to scrape it from the video only..

[@nad1165]

Thank you, and may I ask if I can use the f-stat with only 1 restriction (q=number of restrictions=1?)

[@masoomafarhang864]

How can we code this: rent price= b0+ b1sqrft+b2bdrms+b3sqrft^2+u
Can we code it like: MLRhouseregression=lm(price~sqrft+bdrms+sqrft^2, data=hprice1)?

[@dataexplained7305]

I suggest try the predictor variables in different combinations by adding/dropping them and which ever gets best measures make the decision based on that..

Your video screen is not visible, could you please check it?

[@HarpreetKaur-bx1ej]

I am getting r squared value 0.008569 which is about 0.9% and f stat value is 19.62. getting 0.9% squared values is good or bad please help. As i am confused in this

[@dataexplained7305]

Thanks for the Q..looks like there is very less correlation between your predictor and target .. try switching the features/variables.. and see if the Rsq.value Improves ?
