18 p, 986.2 KB Modelling extreme values by the residual coefficient of variation / Castillo, Joan del (Universitat Autònoma de Barcelona. Departament de Matemàtiques) ; Padilla Cozar, Maria
The possibilities of the use of the coefficient of variation over a high threshold in tail modelling are discussed. The paper also considers multiple threshold tests for a generalized Pareto distribution, together with a threshold selection algorithm. [...]

24 p, 409.1 KB Smoothed landmark estimators of the transition probabilities / Meira-Machado, Luis (University of Minho (Guimaraes, Portugal). Centre of Mathematics and Department of Mathematics and Applications)
One important goal in clinical applications of multi-state models is the estimation of transition probabilities. Recently, landmark estimators were proposed to estimate these quantities, and their superiority with respect to the competing estimators has been proved in situations in which the Markov condition is violated.

26 p, 2.4 MB Log-ratio methods in mixture models for compositional data sets / Comas-Cufí, Marc (Universitat de Girona. Departament d'Informàtica, Matemàtica Aplicada i Estadística) ; Martín-Fernández, Josep-Antoni (Universitat de Girona. Departament d'Informàtica, Matemàtica Aplicada i Estadística) ; Mateu-Figueras, Glòria (Universitat de Girona. Departament d'Informàtica, Matemàtica Aplicada i Estadística)
When traditional methods are applied to compositional data misleading and incoherent results could be obtained. Finite mixtures of multivariate distributions are becoming increasingly important nowadays. [...]

28 p, 700.0 KB Using robust FPCA to identify outliers in functional time series, with applications to the electricity market / Vilar, Juan M. (Universidade da Coruña. Departamento de Matemáticas) ; Raña, Paula (Universidade da Coruña. Departamento de Matemáticas) ; Aneiros, Germán (Universidade da Coruña. Departamento de Matemáticas)
This study proposes two methods for detecting outliers in functional time series. Both methods take dependence in the data into account and are based on robust functional principal component analysis. [...]

36 p, 1.9 MB A construction of continuous-time ARMA models by iterations of Ornstein-Uhlenbeck processes / Arratia, Argimiro (Universitat Politècnica de Catalunya. Departament de Llenguatges i Sistemes Informàtics) ; Cabaña Nigro, Alejandra (Universitat Autònoma de Barcelona. Departament de Matemàtiques) ; Cabaña, Enrique M. (Universidad de la República (Montevideo, Uruguai))
We present a construction of a family of continuous-time ARMA processes based on p iterations of the linear operator that maps a Lévy process onto an Ornstein-Uhlenbeck process. The construction resembles the procedure to build an AR(p) from an AR(1). [...]

24 p, 168.7 KB Kernel-based estimation of P(X >Y) in ranked set sampling / Mahdizadeh, Mahdi (Hakim Sabzevari University (Sabzevar, Iran). Department of Statistics) ; Zamanzade, Ehsan (University of Isfahan (Iran). Department of Statistics)
This article is directed at the problem of reliability estimation using ranked set sampling. A nonparametric estimator based on kernel density estimation is developed. The estimator is shown to be superior to its analog in simple random sampling. [...]

16 p, 140.8 KB Improving the resolution of the simple assembly line balancing problem type E / Corominas, Albert (Universitat Politècnica de Catalunya. Institute of Industrial and Control Engineering) ; García-Villoria, Alberto (Universitat Politècnica de Catalunya. Institute of Industrial and Control Engineering) ; Rafael Pastor, Rafael (Universitat Politècnica de Catalunya. Institute of Industrial and Control Engineering)
The simple assembly line balancing problem type E (abbreviated as SALBP-E) occurs when the number of workstations and the cycle time are variables and the objective is to maximise the line efficiency. [...]
