Velasco, J.M. ; González Pérez, Beatriz ; Minana, Guadalupe ; Lopez, Victoria ; Caro, Raquel | IEEE | 2014Since 1998, the Spanish and Portuguese Administrations began to share a common path in building the Iberian Electricity Market (MIBEL). This cooperation has been very successful, not only for its contribution to the existence of an electricity m[...]texto impreso
Se desarrolla un procedimiento bayesiano para el contraste de homogeneidad de poblaciones multinomiales independientes en tablas de contingencia , cuando el vector de proporciones comunes en la hipótesis nula es conocido, desconocido o de forma [...]texto impreso
In this article the problem of testing if r populations have the same distribution from a Bayesian perspective is studied using r × s contingency tables and ?–contaminated priors. A procedure to build a mixed prior distribution is introduced and[...]texto impreso
The display of the data by means of contingency tables is used in different approaches to statistical inference, for example, to broach the test of homogeneity of independent multinomial distributions. We develop a Bayesian procedure to test sim[...]texto impreso
Gómez Villegas, Miguel A. ; Ausin, A.C ; González Pérez, Beatriz ; Rodríguez-Bernal, María Teresa ; Salazar, I. ; Sanz San Miguel, Luis | Taylor & Francis | 2011Recently, the field of multiple hypothesis testing has experienced a great expansion, basically because of the new methods developed in the field of genomics. These new methods allow scientists to simultaneously process thousands of hypothesis [...]texto impreso
DeGregorio Vicente, Oscar ; González Pérez, Beatriz ; Gómez Villegas, Miguel A. | Asociación Nacional de Ingenieros Industriales de España | 2017Transport planning requires tool to model the current and future situation of an infrastructures network. In this way, different scenarios of passenger flows, vehicles or freight can be predicted and serve as information for decision making. One[...]texto impreso
We develop a Bayesian procedure for the homogeneity testing problem of r populations using r×s contingency tables. The posterior probability of the homogeneity null hypothesis is calculated using a mixed prior distribution. The methodology consi[...]texto impreso
An r x s table is used for different approaches to statistical inference. We develop a Bayesian procedure to test simple null hypotheses versus bilateral alternatives in contingency tables. We consider testing equality of proportions of independ[...]texto impreso
A Bayesian test for H-0: = (0) versus H-1: (0) is developed. The methodology consists of fixing a sphere of radius around (0), assigning to H-0 a prior mass, (0), computed by integrating a density function () over this sphere, and spreading the [...]texto impreso
The display of the data by means of contingency tables is used for discussing different approaches to statistical inference. We develop a Bayesian procedure for the homogeneity testing problem of r populations using r × s contingency tables. Th[...]texto impreso
In this paper the problem of testing a multivariate point hypothesis is considered. Of interest is the relationship between the p-value and the posterior probability. A Bayesian test for simple H0 V ? D ?0 versus bilateral H0 V 6D 0, with a mixe[...]
