In the forthcoming video, we implement multiple linear regression in Python on the same Marketing data but now considering all the three predictors – Radio, TV and Newspaper.
Now, let us solve the same regression problem using normal equations formula with matrix representation and compare the results.
So, in the above video, Anjali built a multiple linear regression model on the marketing data set and verified the results obtained from the normal equations through matrix representation. We also did some residual analysis and verified if the assumptions of linear regression are holding true or not.
