17.6 Use least-squares regression to fit a straight line to 56789 x 1 2 3 4 y 1 1.5 2 3 4 58 10 13 (a) Along with the slope and intercept, compute the standard error of the estimate and the correlation coefficient. Plot the data and the straight line. Assess the fit. (b) Recompute (a), but use polynomial regression to fit a parabola to the data. Compare the results with those of (a). Note: For the first three problems below, you must find the regression fits by writing your own MATLAB functions that calculate the requested values. (1) Problem 17.6. Use the following instructions: a. Determine coefficients for the linear fit, as well as the r² value. b. Show your MATLAB function and Command Window. c. Plot the data and the linear fit.
