A simheuristic for routing electric vehicles with limited driving ranges and stochastic travel times
(Institut d'Estadística de Catalunya, 2019-06-11)
Article
Open AccessGreen transportation is becoming relevant in the context of smart cities, where the use of electric vehicles represents a promising strategy to support sustainability policies. However the use of electric vehicles shows ... -
New L2-type exponentiality tests
(Institut d'Estadística de Catalunya, 2019-06-11)
Article
Open AccessWe 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 ... -
Bayesian joint spatio-temporal analysis of multiple diseases
(Institut d'Estadística de Catalunya, 2019-06-11)
Article
Open AccessIn this paper we propose a Bayesian hierarchical spatio-temporal model for the joint analysis of multiple diseases which includes specific and shared spatial and temporal effects. Dependence on shared terms is controlled ... -
Internalizing negative externalities in vehicle routing problems through green taxes and green tolls
(Institut d'Estadística de Catalunya, 2019-06-11)
Article
Open AccessRoad freight transportation includes various internal and external costs that need to be accounted for in the construction of efficient routing plans. Typically, the resulting optimization problem is formulated as a vehicle ... -
A probabilistic model for explaining the points achieved by a team in football competition. Forecasting and regression with applications to the Spanish competition
(Institut d'Estadística de Catalunya, 2019-06-11)
Article
Open AccessIn the last decades, a lot of research papers applying statistical methods for analysing sports data have been published. Football, also called soccer, is one of the most popular sports all over the world organised in ... -
Automatic regrouping of strata in the goodness-of-fit chi-square test
(Institut d'Estadística de Catalunya, 2019-06-11)
Article
Open AccessPearson’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 ... -
On the optimism correction of the area under the receiver operating characteristic curve in logistic prediction models
(Institut d'Estadística de Catalunya, 2019-06-11)
Article
Open AccessWhen the same data are used to fit a model and estimate its predictive performance, this estimate may be optimistic, and its correction is required. The aim of this work is to compare the behaviour of different methods ... -
Efficient algorithms for constructing D- and I-optimal exact designs for linear and non-linear models in mixture experiments
(Institut d'Estadística de Catalunya, 2019-06-11)
Article
Open AccessThe problem of finding optimal exact designs is more challenging than that of approximate optimal designs. In the present paper, we develop two efficient algorithms to numerically construct exact designs for mixture ...
