Análise e previsão de demanda para vendas em uma indústria da saúde
(Universidade Federal de Santa MariaBrasilUFSMCentro de Tecnologia, 2023-01-31)
Anticipating demand is a technique that underlies the strategic planning of a company, because it enables the optimization of inventories and consequently becomes a differential for each enterprise due to the agility of ...
Sufficient Reductions in Regressions with Exponential Family Inverse Predictors
(American Statistical Association, 2016-07)
We develop methodology for identifying and estimating sufficient reductions in regressions with predictors that, given the response, follow a multivariate exponential family distribution. This setup includes regressions ...
On Wald Residuals in Generalized Linear Models
(TAYLOR & FRANCIS INCPHILADELPHIA, 2012)
A rigorous asymptotic theory for Wald residuals in generalized linear models is not yet available. The authors provide matrix formulae of order O(n(-1)), where n is the sample size, for the first two moments of these ...
INFERENCE FOR EIGENVALUES AND EIGENVECTORS OF GAUSSIAN SYMMETRIC MATRICES
(INST MATHEMATICAL STATISTICS, 2008)
This article presents maximum likelihood estimators (MLEs) and log-likelihood ratio (LLR) tests for the eigenvalues and eigenvectors of Gaussian random symmetric matrices of arbitrary dimension, where the observations are ...
Asymptotic theory for maximum likelihood estimates in reduced-rank multivariate generalized linear models
(Taylor & Francis Ltd, 2018-09)
Reduced-rank regression is a dimensionality reduction method with many applications. The asymptotic theory for reduced rank estimators of parameter matrices in multivariate linear models has been studied extensively. In ...
Sucient dimension reduction and prediction in regression: Asymptotic results
(Elsevier Inc, 2019-03)
We consider model-based sufficient dimension reduction for generalized linear models and prove the consistency and asymptotic normality of the prediction estimator studied empirically for the normal case by Adragni and ...
A q-exponential statistical Banach manifold
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2013-02-15)
Let µ be a given probability measure and Mµ the set of µ-equivalent strictly positive probability densities. In this paper we construct a Banach manifold on Mµ, modeled on the space L 8(p{dot operator}µ) where p is a ...

Stability results for impulsive functional differential equations with infinite delay
(Pergamon-Elsevier B.V. Ltd, 2012-12-01)
For a family of differential equations with infinitive delay and impulses, we establish conditions for the existence of global solutions and for the global asymptotic and global exponential stabilities of an equilibrium ...
