Distribuições discretas zero-modificadas para modelar dados de contagem zeros faltantes
(Universidade Federal de São CarlosUFSCarPrograma Interinstitucional de Pós-Graduação em Estatística - PIPGEsCâmpus São Carlos, 2020-01-24)
The analysis of count data takes an important place in applied statistics, since many real problems are expressed in terms of counts. Frequently, count data sets have discrepancies in the frequency of the zero observation, ...

Modelos série de potência com excesso de zeros observáveis e latentes
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Estatística - PPGEsCâmpus São Carlos, 2016-09-28)
The present work's main objective is to study the significance of zeros in an observable
and latent data. In observable data set that occur excess of zeros, its common to have
sobredispersion. In this sense, the models ...
Zeros da função geradora dos momentos: uma nova abordagem para os zeros da função de partição
(Universidade Federal de Minas GeraisBrasilICX - DEPARTAMENTO DE FÍSICAPrograma de Pós-Graduação em FísicaUFMG, 2021-12-10)
The method of Fisher zeros is used to identify phase transitions without the need to
estimate thermodynamic quantities at various temperatures or define an order parameter. However, this method is difficult to apply in ...

Zero-Hopf bifurcation in the FitzHugh-Nagumo system
(2015-11-30)
We characterize the values of the parameters for which a zero-Hopf equilibrium point takes place at the singular points, namely, O (the origin), P+, and P- in the FitzHugh-Nagumo system. We find two two-parameter families ...
Zeros of Jacobi functions of second kind
(Elsevier B.V., 2006-04-01)
The number of zeros in (- 1, 1) of the Jacobi function of second kind Q(n)((alpha, beta)) (x), alpha, beta > - 1, i.e. The second solution of the differential equation(1 - x(2))y (x) + (beta - alpha - (alpha + beta + 2)x)y' ...
