30 p, 519.8 KB Automatic regrouping of strata in the goodness-of-fit chi-square test / Núñez-Antón, Vicente (Universidad del País Vasco) ; Pérez-Salamero, Juan Manuel (Universitat de València) ; Regúlez-Castillo, Marta (Universidad del País Vasco) ; Ventura-Marco, Manuel (Universitat de València) ; Vidal-Meliá, Carlos (Universitat de València)
Pearson's chi-square test is widely employed in social and health sciences to analyse categorical data and contingency tables. For the test to be valid, the sample size must be large enough to provide a minimum number of expected elements per category. [...]

26 p, 447.4 KB New L2-type exponentiality tests / Cuparić, Marija (University of Belgrade. Faculty of Mathematics) ; Milosević, Bojana (University of Belgrade. Faculty of Mathematics) ; Obradović, Marko (University of Belgrade. Faculty of Mathematics)
We introduce new consistent and scale-free goodness-of-fit tests for the exponential distribution based on the Puri-Rubin characterization. For the construction of test statistics we employ weighted L2 distance between V-empirical Laplace transforms of random variables that appear in the characterization. [...]

In this paper we study a goodness-of-fit test based on the maximum correlation coefficient, in the context of randomly censored data. We construct a new test statistic under general right- censoring and prove its asymptotic properties. [...]

26 p, 204.3 KB A goodness-of-fit test for the multivariate Poisson distribution / Novoa-Muñoz, Francisco (Universidad del Bío-Bío (Xile). Departamento de Estadística) ; Jiménez-Gamero, María Dolores (Universidad de Sevilla. Departamento de Estadística)
Bivariate count data arise in several different disciplines and the bivariate Poisson distribution is commonly used to model them. This paper proposes and studies a computationally convenient goodness-of-fit test for this distribution, which is based on an empirical counterpart of a system ofequations. [...]

34 p, 293.5 KB A test for normality based on the empirical distribution function / Torabi, Hamzeh (Yazd University (Iran). Statistics Department) ; Montazeri, Narges H. (Yazd University (Iran). Statistics Department) ; Grané, Aurea (Universidad Carlos III de Madrid. Departamento de Estadística)
In this paper, a goodness-of-fit test for normality based on the comparison of the theoretical and empirical distributions is proposed. Critical values are obtained via Monte Carlo for several sample sizes and different significance levels. [...]

30 p, 322.7 KB The importance of being the upper bound in the bivariate family / Cuadras, C. M. (Universitat de Barcelona)
Any bivariate cdf is bounded by the Fréchet-Hoeffding lower and upper bounds. We illustrate the importance of the upper bound in several ways. Any bivariate distribution can be written in terms of this bound, which is implicit in logit analysis and the Lorenz curve, and can be used in goodness-of-fit assesment. [...]

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.
