Given the regression equation in 2 forms: (1) yi = B0 + B1xi + ui; (2) yi = xB + ui (where x and B in the 2nd equation are vectors). And both equations are the same. Does vector x = [1 x1] or [x1] (row vector)? Vector B = [B0; B1] (column vector)? Does

Vector B = [B0; B1] (column vector)?
Does
Quantities that have magnitude and direction but not position. Some examples of vectors are velocity, displacement, acceleration, and force. They are sometimes called Euclidean or spatial vectors.
