The maximum deflections of the bridge girder were measured under 10 different truckloads when the loads ranged from 100 kN to 300 kN. The load, (kN), and the associated maximum deflection, (mm), are recorded in Dataset 1 (You can find it on eClass in Lab 7 materials). Based on the as-built condition of the newly constructed highway bridge, an accurate relationship between the truckload (kN) and the deflection (mm), can be achieved by the following theoretical model (denoted as the True Model): True Model: () = 1+2 with 1= 2.0 mm and 2=0.025 mm/kN Find a Linear Model ()=1+2 with optimal model parameters 1 and 2 such that the linear model best fits the dataset. You may use the provided function fitcurve and modify it to suit your needs. - Find the Estimated Model function, including the coefficients (=1,2) and the corresponding coefficient of determination 2 . - Plot the Estimated Model function, the True Model function, and the data points, all in a single graph for comparison. - Plot the residual in each point for the Estimated Model function. The residual is very helpful in model diagnosis (e.g. the residual should be around zero on average, with relatively constant variance). Note: - Report your answers to 4 decimal places. - Use Dataset1 provided. Dataset1.dat: 282.68 8.6 269.84 8.6 255.01 8.5 107.58 4.6 195.43 6.6 200.77 6.6 210.58 7. 211.68 6.8 211.43 7. 271.17 8.3
