Métodos de estimação em modelos de efeitos mistos não lineares de caudas pesadas
(Universidade Federal de São CarlosUFSCarPrograma Interinstitucional de Pós-Graduação em Estatística - PIPGEsCâmpus São Carlos, 2019-12-05)
Parameter estimation in nonlinear mixed-effects models is often challenging. In this thesis,
a comparison of estimation methods for these models is proposed under a frequentist
approach. In the first study, a comparison ...
Modelos não lineares assimétricos com efeitos mistos
(Universidade Federal de São CarlosUFSCarPrograma Interinstitucional de Pós-Graduação em Estatística - PIPGEsCâmpus São Carlos, 2019-08-02)
This work aims to develop asymmetric nonlinear regression models with mixed-effects, which provide alternatives to the use of normal distribution and other symmetric distributions, in order to avoid the sensitivity in the ...
Nonlinear mixed-effects modelling for single cell estimation: When, why, and how to use it
(BioMed Central, 2015-09)
Background: Studies of cell-to-cell variation have in recent years grown in interest, due to improved bioanalytical techniques which facilitates determination of small changes with high uncertainty. Like much high-quality ...
Non-linear mixed models in the study of growth of naturalized chickens

How temperature variation affects white-rot fungi mycelial growth dynamics: A nonlinear mixed models approach
(2021-01-01)
This study aimed to model mycelial growth in a factorial experiment with two species of white rot fungi growing at five temperatures. The nonlinear models evaluated were logistic, Gompertz, Weibull and von Bertalanffy. The ...
Mixed nonlinear models in ruminal in situ degradability trialsModelos não lineares mistos em ensaios de degradabilidade ruminal in situ
(2020-01-01)
Classical methods of analysis of nonlinear models are widely used in studies of ruminal degradation kinetics. As this type of study involves repeated measurements in the same experimental unit, the use of mixed nonlinear ...
