Modelos GARCH Bayesianos: Métodos Aproximados e Aplicações

, 1999
The class of GARCH models is briefly revised and those models reformulated as dynamic Bayesian models. Gaussian quadrature technique and Laplace approximation are used to estimate both static and dynamic GARCH models of moderate dimension.

First‐trimester prediction and prevention of preterm pre‐eclampsia in women with chronic hypertension

Ultrasound in Obstetrics &Gynecology, Volume 67, Issue 5, Page 613-622, May 2026.
ABSTRACT Objectives To evaluate the effect of aspirin on gestational age at delivery due to preterm pre‐eclampsia (PE) in women with chronic hypertension (CH), to assess the predictive performance of the Fetal Medicine Foundation (FMF) first‐trimester competing‐risks model for preterm PE in this high‐risk group and to evaluate how parity, previous PE ...

Use of stochastic patch occupancy models in the California red‐legged frog for Bayesian inference regarding past events and future persistence

Conservation Biology, Volume 33, Issue 3, Page 685-696, June 2019., 2019
Abstract Assessing causes of population decline is critically important to management of threatened species. Stochastic patch occupancy models (SPOMs) are popular tools for examining spatial and temporal dynamics of populations when presence–absence data in multiple habitat patches are available. We developed a Bayesian Markov chain method that extends

A análise de diagnósticos de enfermagem sob uma perspectiva bayesiana

Revista da Escola de Enfermagem da USP, 2012
O uso de técnicas de estatística bayesiana é uma abordagem que tem sido bem aceita e estabelecida em campos fora da enfermagem como um paradigma de redução da incerteza presente em uma dada situação clínica.

Antipoaching standards in onshore hydrocarbon concessions drawn from a Central African case study

Conservation Biology, Volume 31, Issue 3, Page 696-706, June 2017., 2017
Abstract Unsustainable hunting outside protected areas is threatening tropical biodiversity worldwide and requires conservationists to engage increasingly in antipoaching activities. Following the example of ecocertified logging companies, we argue that other extractive industries managing large concessions should engage in antipoaching activities as ...

PhyBaSE: A Bayesian structural equation model approach to causal inference in phylogenetic comparative analyses

Methods in Ecology and Evolution, Volume 16, Issue 6, Page 1136-1148, June 2025.
Abstract One of the main limitations of phylogenetic comparative analyses is that associations between traits can only be interpreted as correlations. Here, we present a novel Bayesian structural equation model (PhyBaSE) which allows us to disentangle direct from indirect relationships among variables to propose potential causal hypotheses while ...

Sequential testing of complementary hypotheses about population density

Methods in Ecology and Evolution, Volume 16, Issue 6, Page 1228-1238, June 2025.
Abstract Making inferences about population density is paramount in ecology and pest management for decision‐makers who often seek to determine how a population compares to a pre‐established static or dynamic threshold through sampling or monitoring. Sequential data analysis is appealing for monitoring and decision making as it is more cost‐efficient ...
