Answer 1

Answer #1

The data given is wrong:

TSS is the total sum of square

RSS is the residual sum of squares

But TSS=RSS+ESS

TSS should be always greater than RSS.[Here it is not so]

Then we find ESS (Explained sum of squares)

Then we find R²=ESS/TSS

Then based on R² value we conclude the goodness of the model.
