Distribuição de valores extremos generalizada inflada de zeros
(BrasilUFRNPROGRAMA DE PÓS-GRADUAÇÃO EM MATEMÁTICA APLICADA E ESTATÍSTICA, 2017-05-05)
Extreme events are usually responsible for producing big gains or big losses to society.
There is already a specific distribution, known as Generalized Extreme Values
Distribution (GEV), developed to predict and prevent ...
Zeros of Jacobi functions of second kind
(Elsevier B.V., 2014)
The influence of zero-value subtraction on the performance of two laser fluorescence devices for detecting occlusal caries in vitro
(2008-08-01)
Background. The aim of this study was to evaluate the influence of zero-value subtraction on the performance of two laser fluorescence (LF) devices developed to detect occlusal caries. Methods. The authors selected 119 ...

Modelos bayesianos zero-modificados para séries temporais de contagem
(Universidade Federal de São CarlosUFSCarPrograma Interinstitucional de Pós-Graduação em Estatística - PIPGEsCâmpus São Carlos, 2020-04-30)
This work presents two Bayesian zero-modified (ZM) models for count time series: zero-modified Poisson ARMA and zero-modified COM-Poisson ARMA. The latter allows a greater flexibility since it has an aditional parameter ...
Linear and bilinear operators and their zero-sets
(Universidad Complutense de Madrid, 2021-01-20)
We study the extent to which several classical results relating linear or multilinear forms and their zero-sets can be generalised to linear or bilinear operators with values in Rn. We find some analogues of the classical ...
Inequalities for zeros of Jacobi polynomials via Sturm's theorem: Gautschi's conjectures
(Springer, 2014-11-01)
Let x(n,k)((alpha,beta)), k = 1, ... , n, be the zeros of Jacobi polynomials P-n((alpha,beta)) (x) arranged in decreasing order on (-1, 1), where alpha, beta > -1, and theta((alpha,beta))(n,k) = arccos x(n,k)((alpha,beta)). ...
Spatio-temporal modelling of coffee berry borer infestation patterns accounting for inflation of zeroes and missing values
(São Paulo - Escola Superior de Agricultura Luiz de Queiroz, 2009)
The study of pest distributions in space and time in agricultural systems provides important information for the optimization of integrated pest management programs and for the planning of experiments. Two statistical ...
