Following are the corrections required:

1. Question (iv) How many predictor variables do we have (Hint: all variables other than mpg)?
   Please correct this answer.

2. Question 4: The question is asking for Root mean square prediction error (also called RMSE) instead of percentage error.

You answer to Question 2 (ii) is correct. It represents the line of best fit, which is defined by the concept of linear regression.

Hi Anjali,
Thank you for pointing out he issues in my assignment. I think I was able to fix them.

Hello Fooroogh,
I noticed that you submitted two files assignment_2_frm.ipynb and assignment_2_frm_a2.ipynb
but neither contains the requested review changes. Please remember that it's unnecessary to change the filename when making review changes. Could you kindly upload a single corrected file named assignment_2.ipynb and remove the other two? If you need help with this, please join the work period where one of the LS staff can help
Thanks!

I pushed assignment-2. I can see the changes now. Could you please check to see if they reflected on your end, too? Thank you!

Hi Anjali,

The question is asking for RMSE, and I calculated RMSE. Could you please help me understand the issue?
Thank you!

[anjali-deshpande-hub]

Hello!
You have calculated 'Root Mean Square Percentage Error'. The question is asking for
RMSE which is an absolute error magnitude (same units as data) rather than relative (percentage) error. The correct answer is

rmse = np.sqrt(mean_squared_error(test_response, y_pred))

Please make the suggested changes. Thank you.

All fixed now. Thank you.
