Question
A certain experiment produces the data
(1, 1.8), (2,2.7), (3, 3.4), (4, 3.8), (5, 3.9)
Describe the model that produces a least-squares fit of these points bya function of the form
у %3D Вух + Вx?
Such a function might arise, for example, as the revenue from the sale of x units of a product, when the amount offered for
sale affects the price to be set for the product.
a. Give the design matrix, the observation vector, and the unknown parameter vector.
b. [M] Find the associated least-squares curve for the data.
