clear explaination sir, thankyou so much

[dr.walidsoula]

Clear explanation of Adjusted R squared 👏

[mukutsharma]

Best and easiest explanation on the internet

[nitinchauhan]

i watch your video today andi got amazed by your skills how you explain simply thankA lot

[souravbiswas]

Awesome explanation, hence comes the concept of parsimonious model, - obtaining higher accuracy with fewer no of predictors..

[dilnawazahmed]

Kya padhate h bhai aap
Maza aa gya 👌👌

[omkarfadtare]

Thanks you explain every concept in simple words which are so easy to understand..🙏👍 and Thanks to the recommendation engine as well which recommended me your channel 😄😄

[lancelotdsouza]

Thanks for the beautiful videos, love your explanations, so simple but yet profound. Can't thank you enough. Your videos are better than paid courses

Based on Rsquared score are we selecting features? Is R squared is a feature selection technique for linear regression?

[fahadnasir]

Thank you for very detailed video, outstanding work Aman.
One questions - When I create model in python with one independent variable, the output shows adjusted R square in it, how will we interpret adjusted R square for a model which has one independent variable?

[rezazaman]

Thanks for such excellent videos.

Just to make my understanding correct about the formula:
R2 = 1 – [(1-R2)*(n-1)/(n-k-1)]

Questions :
1. Is Adj. R2 calculated based on train and test dataset independently or on entire dataset ?

2. model.score(X, y) : are X and y from entire dataset or from X_train, /y_train or from X_test/y_test separately ?

n = is it the total observations in actual dataset or depends on the length of train and test dataset ?

k = X.shape[-1], X from actual dataset or from X_train/y_train?

Thanks Aman.

Hello Aman,
Can u please help me to know if we add some important feature then what will happen to adjusted R square? Is it going to increase or decrease?

[bhavithakusam]

What's the difference between adjusted-r square and feature importance? And when to use them

Actually I have heard of research that indeed employee height influences payrates. Taller workers get more $$$$!
