String-averaging expectation-maximization for maximum likelihood estimation in emission tomography
(Iop Publishing Ltd, 2014-05-01)
We study the maximum likelihood model in emission tomography and propose a new family of algorithms for its solution, called string-averaging expectation maximization (SAEM). In the string-averaging algorithmic regime, the ...

Bootstrap methods for generalized autoregressive moving average models
(Universidade Federal de Minas GeraisUFMG, 2018-06-11)
This final paper aims to find a suitable Bootstrap Method for the Generalized Autoregressive Moving Average Model. The focus is on the Moving Block Bootstrap (MBB) resampling scheme with its performance being evaluated ...
Approximate average head models for EEG source imaging
(Elsevier Science, 2009-12-15)
We examine the performance of approximate models (AM) of the head in solving the EEG inverse problem. The AM are needed when the individual’s MRI is not available. We simulate the electric potential distribution generated ...
Does the better -than- average effect show that people are overconfident?: two experiments
(Universidad de Montevideo, Facultad de Ciencias Empresariales y Economía, Departamento de Economía, 2013)
We conduct two experiments of the claim that people are overconfident, using newtests of overplacement that are based on a formal Bayesian model. Our two experi-ments, on easy quizzes, find overplacement. More precisely, ...
Post-processing of sequential indicator simulation realizations for modeling geologic bodies
(Springer, 2015-02-01)
Sequential indicator simulation realizations contain unavoidable artifacts that are geologically unrealistic. This happens because unlikely types can be drawn randomly from the cumulative distribution and be assigned to a ...
