Midterm v1 EGR 102: Introduction to 4 of 9 Engineering Modelling Midterm v1 Question 3 (30 marks) The data in table l is known to fit the following model: where a and B are parameters. The linearization of eq. (1) is a) Using the concepts of nonlinear regression, complete the table headings of table l (the shaded cells). Then, use the results to set up the equations/matrices in solving for ao and ai. You do not need to solve the system of equations.

Explanation / Answer

1)

The table headings are

x y ln x y ( ln x)^2 y * ln x

2) y = 0.5 +2.17 ln(x) where x = 2.6

y = 0.5+ 2.17 * ln(2.6) = 2.573
