Markovian arrivals in stochastic modelling : a survey and some new results / Artalejo, Jesús R. ; Gómez-Corral, Antonio
This paper aims to provide a comprehensive review on Markovian arrival processes (MAPs), which constitute a rich class of point processes used extensively in stochastic modelling. Our starting point is the versatile process introduced by Neuts (1979) which, under some simplified notation, was coined as the batch Markovian arrival process (BMAP). [...]

On ratio and product methods with certain known population parameters of auxiliary variable in sample surveys / Singh, Housila P. ; Tailor, Ritesh ; Tailor, Rajesh
This paper proposes two ratio and product-type estimators using transformation based on known minimum and maximum values of auxiliary variable. The biases and mean squared errors of the suggested estimators are obtained under large sample approximation. [...]

On the use of simulation methods to compute probabilities : application to the first division Spanish soccer league / Díaz Emparanza, Ignacio ; Núñez-Antón, Vicente ; Universidad del País Vasco
We consider the problem of using the points a given team has in the First Division Spanish Soccer League to estimate its probabilities of achieving a specific objective, such as, for example, staying in the first division or playing the European Champions League. [...]

Bayes linear spaces / Van Den Boogart, Karl-Gerald ; Egozcue, J. J.. ; Pawlowsky-Glahn, Vera
Linear spaces consisting of o-finite probability measures and infinite measures (improper priors and likelihood functions) are defined. The commutative group operation, called perturbation, is the updating given by Bayes theorem; the inverse operation is the Radon-Nikodym derivative. [...]

Optimal inverse Beta(3,3) transformation in kernel density estimation / Bolancé, Catalina
A double transformation kernel density estimator that is suitable for heavy-tailed distributions is presented. Using a double transformation, an asymptotically optimal bandwidth parameter can be calculated when minimizing the expression of the asymptotic mean integrated squared error of the transformed variable.

Application of receiver operating characteristic (ROC) methodology in biological studies on marine resources : sex determination of Paracentrotus lividus (Lamarck, 1816) / Lustres-Pérez, Vicente ; Rodríguez-Álvarez, María Xosé ; Pazos Pata, María ; Fernández-Pulpeiro, Eugenio ; Cadarso-Suárez, Carmen ; Universidade de Santiago de Compostela
The receiver operating characteristic (ROC) curve is usually used in biomedicine as an indicator of the accuracy of diagnostic tests. However, this measure of discrimination has been little used in other areas, such as animal biology or ecology. [...]
