Exhibit 5-4
Biological theory suggests that the relationship between the weight of these animals and their wing length is exponential, i.e. W = α(10)βL, or W = α(e)βL where W is the wing weight and L is the wing length.

-The model W = a + bL cannot be directly compared to a model with a response variable logW using the correlation or the standard error of the residuals, because the scales differ. How would you evaluate your transformed model in Exhibit 5-4 to see if it is an improvement over the linear model?
