19 p, 256.6 KB Glacial refugia and mid-Holocene expansion delineate the current distribution of Castanea sativa in Europe / Roces-Díaz, José V. (Centre de Recerca Ecològica i Aplicacions Forestals) ; Jiménez-Alfaro, Borja (Martin Luther University. Institute of Biology) ; Chytrý, Milan (Masaryk University. Department of Botany and Zoology) ; Díaz-Varela, Emilio R. (Universidade de Santiago de Compostela. ECOAGRASOC)
Areas of Quaternary refugia for tree species have been mainly delineated based on fossil records and phylogeography, but niche modelling can provide useful complementary information. Here we use palaeodistribution modelling to test the main hypotheses about the distribution of Castanea sativa in the Last Glacial Maximum (LGM) and the mid-Holocene in Europe. [...]

20 p, 189.7 KB The exponentiated discrete Weibull distribution / Nekoukhou, Vahid (University of Isfahan. Department of Statistics) ; Bidram, Hamid (University of Isfahan. Department of Statistics)
In this paper, the exponentiated discrete Weibull distribution is introduced. This new generalization of the discrete Weibull distribution can also be considered as a discrete analogue of the exponentiated Weibull distribution. [...]

16 p, 179.8 KB Inference on the parameters of the Weibull distribution using records / Jafari, Ali Akbar (Yazd University (Yazd, Iran). Department of Statistics) ; Zakerzadeh, Hojatollah (Yazd University (Yazd, Iran). Department of Statistics)
The Weibull distribution is a very applicable model for lifetime data. In this paper, we have investigated inference on the parameters of Weibull distribution based on record values. We first propose a simple and exact test and a confidence interval for the shape parameter. [...]

20 p, 153.7 KB Estimators for the parameter mean of Morgenstern type bivariate generalized exponential distribution using ranked set sampling / Tahmasebi, Saeid (Persian Gulf University (Bushehr, Iran). Department of Statistics) ; Akbar Jafari, Ali (Yazd University (Yazd, Iran). Department of Statistics)
In situations where the sampling units in a study can be more easily ranked based on the measurement of an auxiliary variable, ranked set sampling provides unbiased estimators for the mean of a population that are more efficient than unbiased estimators based on simple random sampling. [...]

28 p, 632.5 KB The new class of Kummer beta generalized distributions / Pescim, R. R. (Universidade de Sao Paulo-USP. Departamento de Ciências Exatas) ; Cordeiro, G. M. (Universidade Federal de Pernambuco-UFPE. Departamento de Estatística) ; Demétrio, C. G. B. (Universidade de Sao Paulo-USP. Departamento de Ciências Exatas) ; Ortega, E. M. M. (Universidade de Sao Paulo-USP. Departamento de Ciências Exatas) ; Nadarajah, Saralees (University of Manchester. School of Mathematics)
Ng and Kotz (1995) introduced a distribution that provides greater flexibility to extremes. We define and study a new class of distributions called the Kummer beta generalized family to extend the normal, Weibull, gamma and Gumbel distributions, among several other well-known distributions. [...]
