Linear Regression and x0
For our linear regression implementation, do we include x0 in as part of our original X matrix? If we do, that means our original vector X=(x0, x1, x2) would then be transposed to XT=(x2, x1, x0).

Without x0=1, our line (or hyperplane) would be constrained to go through the origin, which would very rarely be useful.
