Figure 1. Illustration of a first-order Taylor linearization of a hypothetical population allometric equation for resting energy expenditure (REE): Inline graphic when Inline graphic, Inline graphic and Inline graphic.

Figure 1

The linearization well approximates expected population REE given total values of body mass Inline graphic in the vicinity of Inline graphic. Therefore, given ‘noisy’ sample data with mean Inline graphic, the linear regression model Inline graphic is an estimate of the first-order Taylor series Inline graphic for the true population modelInline graphic.
