The application of the Gompertz model to describe body growth.

Three potential errors in applying the Gompertz growth model are discussed: 1. Restriction of growth data to the subadult or juvenile phase; 2. Confusion of mean growth rate with (mean) maximum growth rate; 3. Improper application of the growth model in cases of sample size variation. These errors are demonstrated on the example of growth data of Zambian common mole-rats (Cryptomys sp.).
