A bivariate F distribution with marginals on arbitrary numerator and denominator degrees of freedom, and related bivariate beta and t distributions
Journal of the Italian Statistical Society - - 2009
A. H. El-Bassiouny, M. C. Jones
Nonparametric semi-supervised classification with application to signal detection in high energy physics
Journal of the Italian Statistical Society - Tập 31 - Trang 531-550 - 2021
Alessandro Casa, Giovanna Menardi
Model-independent searches in particle physics aim at completing our knowledge of the universe by looking for new possible particles not predicted by the current theories. Such particles, referred to as signal, are expected to behave as a deviation from the background, representing the known physics. Information available on the background can be incorporated in the search, in order to identify po...... hiện toàn bộ
Bahadur efficiency and local optimality of a test for the exponential distribution based on the gini statistic
Journal of the Italian Statistical Society - Tập 5 - Trang 163-175 - 1996
Ya. Yu. Nikitin, A. V. Tchirina
The sample scale-free Gini index is known to be a powerful test of exponentiality against a broad class of alternatives. To understand better the efficiency properties of this test we calculate its Bahadur efficiency for most commonly used parametric alternatives to the exponential distribution. Using variational arguments and the Bahadur-Raghavachari inequality for exact slopes we find the condit...... hiện toàn bộ
Benchmarking techniques for reconciling Bayesian small area models at distinct geographic levels
Journal of the Italian Statistical Society - Tập 26 - Trang 557-581 - 2017
Ryan Janicki, Andrew Vesper
In sample surveys, there is often insufficient sample size to obtain reliable direct estimates for parameters of interest for certain domains. Precision can be increased by introducing small area models which ‘borrow strength’ by connecting different areas through use of explicit linking models, area-specific random effects, and auxiliary covariate information. One consequence of the use of small ...... hiện toàn bộ
Identifiability conditions for Generalised STARMA models
Journal of the Italian Statistical Society - Tập 6 - Trang 245-255 - 1997
Giuseppina Guagnano, Silvia Terzi
In this paper, starting from some well known results for the structural identifiability of VARMA models of given maximum time lagsp andq, we derive parametric conditions which guarantee the identification of Generalized STARMA models.
Statistical dimension estimation in singular spectrum analysis

Scale-constrained approaches for maximum likelihood estimation and model selection of clusterwise linear regression models
Journal of the Italian Statistical Society - Tập 29 - Trang 49-78 - 2019
Roberto Di Mari, Roberto Rocci, Stefano Antonio Gattone
We consider an equivariant approach imposing data-driven bounds for the variances to avoid singular and spurious solutions in maximum likelihood estimation of clusterwise linear regression models. We investigate its use in the choice of the number of components and we propose a computational shortcut, which significantly reduces the computational time needed to tune the bounds on the data. In the ...... hiện toàn bộ
An extension of the standardized randomized response technique to a multi-stage setup
Journal of the Italian Statistical Society - Tập 21 - Trang 475-484 - 2012
Andreas Quatember
If nonresponse and/or untruthful answering mechanisms occur, analyzing only the available cases may substantially weaken the validity of sample results. The paper starts with a reference to strategies of empirical social researchers related to respondent cooperation in surveys embedding the statistical techniques of randomized response in this framework. Further, multi-stage randomized response te...... hiện toàn bộ
