Uma medida de contribuição local para sequências de processos fora de regime permanente
(Universidade Federal de Minas GeraisUFMG, 2015-04-30)
In this work we let us consider a set with a finite number of sequences, discrete and continuous. The main goal in this work is to measure instantaneously the contribution of each sequence of this set to the marginal ...
A method to obtain new copulas from a given one
(Springer Verlag Berlín, 2005-04)
Given a strictly increasing continuous function φ from [0, 1] to [0, 1] and its pseudo-inverse φ[−1], conditions that φ must satisfy for C φ (x1, . . . ,xn)=φ[−1](C(φ(x1), . . . ,φ(xn))) to be a copula for any copula C are ...
Evolution of the Southwestern Angolan Margin: episodic burial and exhumation is more realistic than long-term denudation
(2018-01-01)
There are two main points of view regarding how continental margins evolve. The first one argues that the present-day margins have been developed by long-term denudation since a major exhumation episode, probably driven ...
Asymptotic behavior of robust estimators in partially linear models with missing responses: The effect of estimating the missing probability on the simplified marginal estimators
(Springer, 2011-11)
In this paper, we consider a semiparametric partially linear regression model where missing data occur in the response. We derive the asymptotic behavior of the robust estimators for the regression parameter and of the ...
The age of the Tunas formation in the Sauce Grande basin-Ventana foldbelt (Argentina): Implications for the Permian evolution of the southwestern margin of Gondwana
(Elsevier, 2013-08)
New SHRIMP radiogenic isotope dating on zircons in tuffs (280.8 1.9 Ma) confirms the Early Permian (Artinskian) age of the uppermost section of the Tunas Formation. Tuff-rich levels in the Tunas Formation are exposed in ...
Intellectual property rights and international trade of agricultural products
(Elsevier, 2016-04)
The signing of the agreement on Trade-Related Aspects on Intellectual Property Rights (TRIPS) had led to a process of global harmonization and tightening of intellectual property rights (IPRs) systems. As part of this ...
Plug-in marginal estimation under a general regression model with missing responses and covariates
(Springer, 2018-06)
In this paper, we consider a general regression model where missing data occur in the response and in the covariates. Our aim is to estimate the marginal distribution function and a marginal functional, such as the mean, ...
