SECTION 6.6 LINEAR MODELS EXAMPLE. An experiment produces the xy -data points (1 , 1) , (2 , 2) , (3 , 4) , (5 , 5). Find the equation y = β 0 + β 1 x of the least-squares line that best ﬁts these data points. Along the way, note the design matrix X , the parameter vector β , the observation vector y , and why it’s called the least-squares line.

Unformatted text preview: , 3 . 4) , (4 , 3 . 8) , (5 , 3 . 9) and theory says these data should lie along a curve given by y = β 1 x + β x x 2 . We want to produce a least-squares ﬁt by such a curve. Give the design matrix, the observation vector, and the unknown parameter vector. Then ﬁnd the least-squares curve. HOMEWORK: SECTION 6.6...
