The multiplicative heteroscedastic Von Bertalanffy model

In this work we propose a heteroscedastic Von Bertalanffy growth model considering a multiplicative heteroscedastic dispersion matrix. All estimates were obtained through a sampling based approach, which allows information to be input beforehand with lower computational effort. Simulations where realized in order to verify some frequentist properties of the estimation procedure in presence of small and moderate sample sizes. The methodology is illustrated on a real Kubbard female chicken corporeal weight dataset. Key word: Growth Models, Multiplicative Heteroscedasticity, Bayesian Analysis, Simulation.
