Abstract
The paper presents data on possibilities to extrapolate results obtained when extending four most commonly used length growth mathematical models (the binomial, von Bertalanffy equation, Gompertz equation, and Ford-Walford model) beyond the range of empirical data. The technique used involved calculating a model from a part of empirical data only and comparing the extrapolated results obtained with the rest of the empirical data. The extrapolated results were deemed accurate enough if a difference between then and the corresponding empirical values did not exceed 5%.
