Multiple Linear Regression using python ( Regression Analysis )

[@ahcai8578]

Hi Sir, for the region can we use get_dummies instead of the ordinal way(0,1,2,3)? Thank you.

Region is actually considered as nominal because regions don’t really have any ranks. But using get dummies we have chances to end-up with multicollinearity. Instead i converted them to 0,1,2,3. You can try using dummies and check the correlation matrix to see if there is any multicollinearity.

@@MLwithme1617 thanks Sir, I will try it. Thanks for the video, it is great!

@@MLwithme1617 I think we can use dummies method and remove any one column that will work right?

Hi Sir, can you do a video tutorial on how can you improve the r2 score? Thank you

How do we calculate Mean Square Error (MSE) for this. after all the calculation?

Use MSE from sklearn, or for better understanding the math you can have a look at my explanation video on MSE.
