Chapter 13 - Nonlinear Relationships

• Fitting an exponential model with Minitab
  • How do you transform y=ab^x to create a linear function?
  • Illustration of this transformation with Exercise 17 on p. 534 - see Cyclist.MTW
• Fitting a logistic regression model with Minitab
  • We need to deal with the logit transformation, p-hat = exp(a+bx)/[1+exp(a+bx)].
  • Exercise 27 on p. 537 - see SuperBowl2010.MTW
• In class exercises - 22 on p. 535 and 23 on p. 536.
