Markovian arrivals in stochastic modelling: a survey and some new results
(Institut d'Estadística de Catalunya, 2010)
Article
Open AccessThis 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 ... -
On ratio and product methods with certain known population parameters of auxiliary variable in sample surveys
(Institut d'Estadística de Catalunya, 2010)
Article
Open AccessThis 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 ... -
On the use of simulation methods to compute probabilities: application to the first division Spanish soccer league
(Institut d'Estadística de Catalunya, 2010)
Article
Open AccessWe 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 ... -
Bayes linear spaces
(Institut d'Estadística de Catalunya, 2010)
Article
Open AccessLinear spaces consisting of -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 ... -
Optimal inverse Beta(3,3) transformation in kernel density estimation
(Institut d'Estadística de Catalunya, 2010)
Article
Open AccessA 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 ... -
Application of receiver operating characteristic (ROC) methodology in biological studies on marine resources: sex determination of Paracentrotus lividus (Lamarck, 1816)
(Institut d'Estadística de Catalunya, 2010)
Article
Open AccessThe 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 ...
