High proportion of smaller ranged hummingbird species coincides with ecological...
Sonne, Jesper; Martín González, Ana M.; Maruyama, Pietro Kiyoshi; Sandel, Brody S.; Vizentin-Bugoni, Jeferson; Schleuning, Matthias; Abrahamczyk, StefanEcological communities that experience stable climate conditions have been speculated to preserve more specialized interspecific associations and have higher proportions of smaller ranged species (SRS). Thus, areas with disproportionally large numbers of SRS are expected to coincide geographically with a high degree of community-level ecological specialization, but this suggestion remains poorly supported with ...

6174: um problema com números de quatro algarismos
Oliveira, Paulo E.Aborda-se um problema clássico da chamada matemática recreativa. Uma operação definida para números com quatro algarismos, com pelo menos um distinto dos outros, é tal que, quando iterada, converge rapidamente para o número mágico 6174. Apresentamos uma descrição completa do número de iterações necessárias para se chegar ao 6174 e calcula-se o número esperado de iterações quando escolhemos arbitrariamente o núme...

On the kernel estimation of a multivariate distribution function under positive...
Azevedo, Cecília Maria; Oliveira, Paulo E.In this paper, we consider the kernel estimator of the p-dimensional marginal distribution function of a stationary, positively associated sequence of random variables. For this setting, we state results concerning the asymptotic behaviour of this estimator extending some characterizations available in the literature. In addition, we present a simulation study about the empirical process constructed from such a...
On the multivariate kernel distribution estimator for distribution functions un...
Azevedo, Cecília Maria; Oliveira, Paulo E.In this note we consider the estimation of the multivariate distribution function Fp of the p-dimensional marginal of a stationary associated sequence. We show, under certain regularity conditions, the almost sure consistency and characterize the asymptotic behavior of the MSE. We also characterize the asymptotic optimal bandwidth. Under some stronger assumptions on the covariance this bandwidth rate is shown t...
