Given the following data: x1x2 y 4 rows x 3 columns suppose we want to model y using a linear model, 5! = Aw where w is the coefficient vector including the intercept of the linear model, and A is constructed by concatenating a ones column and the data X. We know that we can solve for w by forming the normal equations ATAW = ATy and solving as we would any system of linear equations. Without doing an)r matrix multiplication or inversion, show the entries of A: l l l l a
