The linear model to be employed in the experiment is based on linear regression using least-squares studied in Sec. 1.3.1, see pages 26-29 of the course notes. Below we summarize the method where the items involved are explicitly specified in accordance with the above mentioned dataset. The linear model is given by y = wx+b (E1.1) where yR, WER6x1, x = R 6x1, and be R. With training data {(x,y,), p = 1, 2,..., 314} (see Sec. 2.3 below), we construct = x tr 1 y X2 ... 1 X314 1 y2 and y = (E1.2) 17x314 Y314 The linear model to be employed in the experiment is based on linear regression using least-squares studied in Sec. 1.3.1, see pages 26-29 of the course notes.
