linear algebra calculus Suppose we have this data (Lay, Linear Algebra 3rd ed.): X Y We presume there's a linear relationship between X and Y. That means we can write (10) We are looking for A), 1-You can think of the A) as a kind of bias and is roughly the ratio of Y to X. Writing these as matrices: Bo (12) 3 (13) 3 (14) We are solving: (15) You should practice your matrix multiplication to verify you're looking at these equations (16) (17) (18) (19)
