Objective and subjective prior distributions for the gompertz distribution
(2018-07-01)
This paper takes into account the estimation for the unknown parameters of the Gompertz distribution from the frequentist and Bayesian view points by using both objective and subjective prior distributions. We first derive ...
Modelo de Gompertz com sazonalidade e autocorrelação nos erros para ajuste do crescimento ponderal em vaca leiteira
(Empresa Brasileira de Pesquisa Agropecuária (EMBRAPA), 1994-05-01)
In recent work (Kroll, 1990) on dairy cattle growth using its monthly weights, a Gompertz function, first considering the autocorrelated error structure, and second, the independent error structure, was fitted. The last ...

Deposição de nutrientes na carcaça de girinos de rã-touro
(Empresa Brasileira de Pesquisa Agropecuária (EMBRAPA), 2013-08-01)
The objective of this work was to determine nutrient deposition on the carcass of bullfrog (Lithobates catesbeianus) tadpoles using a nonlinear model. A total of 2,700 tadpoles with an average weight of 0.039 g were used. ...
Lazer–Leach conditions for coupled Gompertz-like delayed systems
(Pergamon-Elsevier Science Ltd, 2018-09)
A coupled Gompertz-like system of delay differential equations is considered. We prove the existence of T-periodic solutions under resonance assuming a Lazer–Leach type condition.
