Repeat the analysis of Problem 14.8 for the dependent variable F, using starting values b1 = 5, b2 = 1.6, b3 = 300, and b4 = .05. Then repeat starting from b3 = 200 and keeping the other starting values the same.

Finally, repeat starting from b3 = 100. Discuss the results of these three attempts. Contrast this result to the result of Problem 14.8. Use Marquardt’s method. (The data are in Table D-48, Appendix D.)
