Question:

For the data sets below, calculate the following.

The linear regression surface. Use matrix regression.

The square of the standard error, s²_e.

(a) D = {(42, 79, 1056), (62, 51, 564), (57, 47, 507), (37, 49, 655), (17, 26, 337), (39, 78, 1155), (43, 43, 593), (20, 13, 174), (97, 52, 485), (82, 94, 1158)}.

(b) D = {(101.6, 64.8, 91.5), (14.9, 37.6, 66.6), (37.9, 48.9, 84.8), (−23.7, 28.4, 91.4), (8.7, 33.5, 43.6), (43.1, 16.5, 93.3), (44.3, 32.6, 65.)}.

(c) D = {(−8.5, 22.8, 73.1), (−10.8, 14.8, 69.3), (−5.8, 24.6, 74.9), (−12.9, 20.8, 71.5), (−10.5, 18.9, 75.3)}.
