ADBD - Anàlisi de Dades Complexes per a les Decisions Empresarials
Realitzar recerca, innovació i transferència de tecnologia en mètodes estadístics aplicats a la indústria, els serveis i a altres àrees del coneixement científic.
The group does research and knowledge transfer in three areas:
a) Industrial Statistics, with applications to improve the quality and productivity of industrial processes, industrial logistics, forecasting, quality management and improvement (Six Sigma) and the emotional design of products (Kansei Engineering).
b) The use of analytics in business and industrial environments. We are working on customer characterization and Churn (early detection of abandonment) and reliability and preventive maintenance of remote machines.
c) The analysis of complex data, discrete and often dependent spatial and / or temporal applications of Bayesian nonparametric methods and engineering and analysis of election results, demographics, ecology, and the statistical analysis of literary style.
d) Better ways to teach statistics to university students and also to business and industry professionals

Outlier detection for multivariate categorical data
(2018)
Article
Accés restringit per política de l'editorialThe detection of outlying rows in a contingency table is tackled from a Bayesian perspective, by adapting the framework adopted by Box and Tiao for normal models to multinomial models with random effects. The solution ... -
Functional regression on remote sensing data in oceanography
(2018-06-01)
Article
Accés obertThe aim of this study is to propose the use of a functional data analysis approach as an alternative to the classical statistical methods most commonly used in oceanography and water quality management. In particular we ... -
Cokriging and multivariate kriging methods based on data of a functional random field
(2017-12-23)
Article
Accés obertKriging and cokriging and their several related versions are techniques widely known and used in spatial data analysis. However, when the spatial data are functions a bridge between functional data analysis and geostatistics ... -
A bayesian test for Hardy-Weinberg equilibrium of bi-allelic X-chromosomal markers
(2017-07)
Article
Accés obertThe X chromosome is a relatively large chromosome, harboring a lot of genetic information. Much of the statistical analysis of X-chromosomal information is complicated by the fact that males only have one copy. Recently, ... -
Choosing the most relevant level sets for depicting a sample of densities
(2017-09-01)
Article
Accés obertWhen exploring a sample composed with a set of bivariate density functions, the question of the visualisation of the data has to front with the choice of the relevant level set(s). The approach proposed in this paper ... -
CHROMA: a maturity model for the information-driven decision-making process
(2017)
Article
Accés restringit per política de l'editorialA novel maturity model for the information-driven decision-making process (DMP) in organisations is presented. The 'circumplex hierarchical representation of organisation maturity assessment' (CHROMA) model was developed ... -
Puntos de servicio en aseos públicos para minimizar y equilibrar los tiempos de espera de hombres y mujeres
(Consejo Superior de Investigaciones Científicas (CSIC), 2017-07-01)
Article
Accés obertThe article raises the issue of the queues that usually appear in the ladies toilets in contrast to the fluidity with which gentlemen can access theirs, and points that this situation is only due to bad dimensioning of the ... -
Measuring non-linear dependence for two random variables distributed along a curve
(2009-09)
Article
Accés obertWe propose new dependence measures for two real random variables not necessarily linearly related. Covariance and linear correlation are expressed in terms of principal components and are generalized for variables distributed ... -
Puntos de servicio en aseos públicos para minimizar y equilibrar los tiempos de espera de homb res y mujeres
(Consejo Superior de Investigaciones Científicas (CSIC), 2017-04)
Article
Accés obertSe plantea el problema de las colas que se presentan habitualmente en los aseos de señoras en contraste con la fluidez con que se accede a los de caballeros, considerando que esta situación tiene solución ya que es sólo ... -
Blocking versus robustness in industrial contexts
(2017-01-01)
Article
Accés obertThe paper discusses the similarities and differences between blocking factors (blocked designs) and noise factors (robust designs) in industrial two-level factorial experiments. The discussion covers from the objectives ... -
Estimating missing values from negligible interactions in factorial designs
(2017-01-01)
Article
Accés obertWhen a factorial design has some missing value but there are contrasts (at least as many as there are missing values) corresponding to interactions that can be considered negligible, equating the expressions of those ... -
Visualizing type II error in normality tests
(2018-01-26)
Article
Accés obertA Skewed Exponential Power Distribution, with parameters defining kurtosis and skewness, is introduced as a way to visualize Type II error in normality tests. By varying these parameters a mosaic of distributions is built, ...
