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

[@MLwithme1617]

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

[@amirman6531]

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

[@MLwithme1617]

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