Oakland (CA) airport


Airline passengers revisited. In Chapter 9, Exercise 9, we created a linear model describing the trend in the number of passengers departing from the Oakland (CA) airport each month since the start of 1997. Here’s the residual plot, but with lines added to show the order of the values in time:

 

a) Can you account for the pattern shown here?

b) Would a re-expression help us deal with this pattern? Explain.

Exercise 9

Oakland passengers. The scatterplot below shows the number of passengers departing from Oakland (CA) airport month by month since the start of 1997. Time is shown as years since 1990, with fractional years used to represent each month. (Thus, June of 1997 is 7.5—halfway through the 7th year after 1990.) www.oaklandairport.com

a) Interpret the slope and intercept of the model.

b) What does the value of say about the model?

c) Interpret in this context.

d) Would you use this model to predict the numbers of passengers in 2010 Explain.

e) There’s a point near the middle of this time span with a large negative residual. Can you explain this outlier?
