18 p, 324.1 KB Small-sample inference about variance and its transformations / Longford, Nicholas T. ; SNTL Statistics Research and Consulting
We discuss minimum mean squared error and Bayesian estimation of the variance and its common transformations in the setting of normality and homoscedasticity with small samples, for which asymptotics do not apply. [...]

24 p, 373.3 KB Variance reduction technique for calculating value at risk in fixed income portfolios / Abad, Pilar ; Benito, Sonia
Financial institutions and regulators increasingly use Value at Risk (VaR) as a standard measure for market risk. Thus, a growing amount of innovative VaR methodologies is being developed by researchers in order to improve the performance of traditional techniques. [...]

20 p, 178.3 KB A family of ratio estimators for population mean in extreme ranked set sampling using two auxiliary variables / Haq, Abdul ; Shabbir, Javid ; Quaid-i-Azam University
In this paper we have adopted the Khoshnevisan et al. (2007) family of estimators to extreme ranked set sampling (ERSS) using information on single and two auxiliary variables. Expressions for mean square error (MSE) of proposed estimators are derived to first order of approximation. [...]

12 p, 1.0 MB Modelling spatial patterns of distribution and abundance of mussel seed using Structured Additive Regression models / Pazos Pata, María ; Rodríguez-Álvarez, María Xosé ; Lustres-Pérez, Vicente ; Fernández-Pulpeiro, Eugenio ; Cadarso-Suárez, Carmen
As mussel farming depends on sources of natural mussel seed, knowledge of factors is required to regulate both the spatial distribution and abundance of this resource. These spatial patterns were modelled using Bayesian STructured Additive Regression (STAR) models for categorical data, based on a mixed-model representation. [...]

16 p, 181.3 KB New aging properties of the Clayton-Oakes model based on multivariate dispersion / Arias-Nicolás, José Pablo ; Mulero, Julio ; Núñez-Barrera, Olga ; Suárez-Llorens, Alfonso
In this work we present a recent definition of Multivariate Increasing Failure Rate (MIFR) based on the concept of multivariate dispersion. This new definition is an extension of the univariate characterization of IFR distributions under dispersive ordering of the residual lifetimes. [...]
