20 p, 774.1 KB Locally adaptive density estimation on Riemannian manifolds / Henry, Guillermo (Universidad de Buenos Aires. Facultad de Ciencias Exactas y Naturales) ; Muñoz, Andrés (Universidad de Buenos Aires. Facultad de Ciencias Exactas y Naturales) ; Rodriguez, Daniela (Universidad de Buenos Aires. Facultad de Ciencias Exactas y Naturales)
In this paper, we consider kernel type estimator with variable bandwidth when the random variables belong in a Riemannian manifolds. We study asymptotic properties such as the consistency and the asymptotic distribution. [...]

22 p, 317.3 KB Selection and pattern mixture models for modelling longitudinal data with dropout: An application study / Satty, Ali (University of KwaZulu-Natal. School of Mathematics, Statistics and Computer Science (Pietermaritzburg, Sud-àfrica)) ; Mwambi, H. (University of KwaZulu-Natal. School of Mathematics, Statistics and Computer Science (Pietermaritzburg, Sud-àfrica))
Incomplete data are unavoidable in studies that involve data measured or observed longitudinally on individuals, regardless of how well they are designed. Dropout can potentially cause serious bias problems in the analysis of longitudinal data. [...]

22 p, 227.7 KB A nonparametric visual test of mixed hazard models / Spreeuw, Jaap (City University London. Faculty of Actuarial Science and Insurance, Cass Business School) ; Perch Nielsen, Jens (City University London. Faculty of Actuarial Science and Insurance, Cass Business School) ; Fiig Jarner, Søren (Danish Labour Market Supplementary Pension Fund)
We consider mixed hazard models and introduce a new visual inspection technique capable of detecting the credibility of our model assumptions. Our technique is based on a transformed data approach, where the density of the transformed data should be close to the uniform distribution when our model assumptions are correct. [...]

14 p, 162.2 KB Quantile estimation of the rejection distribution of food products integrating assessor values and interval-censored consumer data / Langohr, Klaus (Universitat Politècnica de Catalunya. Departament d'Estadística i Investigació Operativa) ; Gómez Melis, Guadalupe (Universitat Politècnica de Catalunya. Departament d'Estadística i Investigació Operativa) ; Hough, Guillermo (Instituto Superior Experimental de Tecnología Alimentaria. Departamento de Evaluación Sensorial de Alimentos)
Fitting parametric survival models with interval-censored data is a common task in survival analysis and implemented in many statistical software packages. Here, we present a novel approach to fit such models if the values on the scale of interest are measured with error. [...]

22 p, 230.3 KB An alternative to Kim and Warde's mixed randomized response model / Singh, Housila P. ; Tarray, Tanveer A. (Vikram University. School of Studies in Statistics)
When open or direct surveys are about sensitive matters (e. g. gambling habits, addiction to drug and others intoxicants, alcoholism, proneness to tax invasion, induced abortions, drunken driving, history of past involvement in crimes, and homosexuality), non-response bias and response bias become serious problems because people oftentimes do not wish to give correct information.

20 p, 656.9 KB Double bounded Kumaraswamy-power series class of distributions / Bidram, Hamid (University of Isfahan (Irán). Department of Statistics) ; Nekoukhou, Vahid (University of Isfahan (Irán). Department of Statistics)
In this paper, we will introduce the new Kumaraswamy-power series class of distributions. This new class is obtained by compounding the Kumaraswamy distribution of Kumaraswamy (1980) and the family of power series distributions. [...]

8 p, 112.1 KB Analysis of inequality in fertility curves fitted by gamma distributions / Ramos, Héctor M. ; Peinado, Antonio ; Ollero, Jorge ; Ramos, María G. (Universidad de Cádiz. Departamento de Estadística e Investigacíon Operativa)
The aim of this paper is to analyse fertility curves from a novel viewpoint, that of inequality. Through sufficient conditions that can be easily verified, we compare inequality, in the Lorenz and Generalized Lorenz sense, in fertility curves fitted by gamma distributions, thus achieving a useful complementary instrument for demographic analysis.
