24 p, 154.6 KB Likelihood for random-effect models (invited article) / Lee, Youngjo (Seoul National University) ; Nelder, John A. (Imperial College London)
For inferences from random-effect models Lee and Nelder (1996) proposed to use hierarchical likelihood (h-likelihood). It allows inference from models that may include both fixed and random parameters. [...]
The new framework allows likelihood inferences to be drawn for a much wider class of models.
Per a la inferència en models amb efectes aleatoris Lee i Nelder (1996) proposaren utilitzar la versemblança jeràrquica (h-versemblanc¸a). Aquesta permet la inferència en models que presenten a la vegada paràmetres fixos i aleatoris. [...]

18 p, 145.2 KB Muliere and Scarsini's bivariate Pareto distribution: sums, products, and ratios / Nadarajah, Saralees (University of Nebraska) ; Kotz, Samuel (The George Washington University)
We derive the exact distributions of R = X + Y, P = X Y and W = X/(X + Y) and the corresponding moment properties when X and Y follow Muliere and Scarsini's bivariate Pareto distribution. The expressions turn out to involve special functions. [...]
Trobem la distribució exacta de R = X + Y , P = X Y, W = X/(X + Y ), els corresponents moments i les seves propietats quan X, Y segueixen la distribució bivariant Pareto de Muliere i Scarsini. Les expressions fan servir funcions especials. [...]

16 p, 244.1 KB On the role played by the fixed bandwidth in the Bickel-Rosenblatt goodness-of-fit test / Tenreiro, Carlos (Universidade de Coimbra)
For the Bickel-Rosenblatt goodness-of-fit test with fixed bandwidth studied by Fan (1998) we derive its Bahadur exact slopes in a neighbourhood of a simple hypothesis f =f0 and we use them to get a better understanding on the role played by the smoothing parameter in the detection of departures from the null hypothesis. [...]
Per al contrast de bondat d'ajust de Bickel-Rosenblatt amb amplada de banda fixa, estudiat per Fan (1998), derivem la seva pendent exacta de Bahadur en un entorn d'una hipòtesi simple f = f0 i la utilitzem per obtenir un coneixement millor del paper del paràmetre suavitzador en la detecci'o de desviacions de la hipòtesi nul·la.

18 p, 128.3 KB On sequential and fixed designs for estimation with comparisons and applications / Terbeche, Mekki (University of Oran) ; Oluyede, Broderick O. (Georgia Southern University) ; Barbour, Ahmed (U.A.E. University)
A fully sequential approach to the estimation of the difference of two population means for distributions belonging to the exponential family of distributions is adopted and compared with the best fixed design. [...]
Adoptem un plantejament complet i exhaustiu per estudiar les diferències entre les mitjanes poblacionals per a distribucions de la família exponencial, que comparem amb el millor disseny d'efectes fixs. [...]

14 p, 126.3 KB On the probability of reaching a barrier in an Erlang(2) risk process / Claramunt Bielsa, M. Mercè 1964- (Universitat de Barcelona) ; Mármol, Maite (Universitat de Barcelona) ; Lacayo, Ramon A. (Universitat Autònoma de Barcelona)
In this paper the process of aggregated claims in a non-life insurance portfolio as defined in the classical model of risk theory is modified. The Compound Poisson process is replaced with a more general renewal risk process with interoccurrence times of Erlangian type. [...]

20 p, 210.6 KB Factorial experimental designs and generalized linear models / Dossou-Gbété, Simplice (Université de Pau et des Pays de l'Adour) ; Tinsson, Walter (Université de Pau et des Pays de l'Adour)
This paper deals with experimental designs adapted to a generalized linear model. We introduce a special link function for which the orthogonality of design matrix obtained under Gaussian assumption is preserved. [...]
Aquest article tracta de dissenys experimentals adaptats al model lineal generalitzat. Introduïm una funció enllac¸ que mant'e l'ortogonalitat de la matriu de disseny obtinguda sota distribució Gaussiana. [...]

20 p, 245.6 KB A comparison of parametric models for mortality graduation. Application to mortality data of the Valencia Region (Spain) / Debón, Ana M. (Universidad Politécnica de Madrid) ; Montes, Francisco (Universitat de València) ; Sala, Ramon (Universitat de València)
The parametric graduation of mortality data has as its objective the satisfactory estimation of the death rates based on mortality data but using an age-dependent function whose parameters are adjusted from the crude rates obtainable directly from the data. [...]
La gradualització paramètrica de dades de mortalitat té com a objectiu l'estimació correcta de taxes de mort a partir de les dades de mortalitat mitjançant una funció que depèn de l'edat, els paràmetres de la qual s'ajusten a partir de les taxes "brutes" de mortalitat obtingudes directament de les dades.
