Small area estimation of labour force indicators under a multinomial model with correlated time and area effects
(Wiley-Blackwell Publishing Ltd., 2014-09-30)
[Abstract] The aim of the paper is the estimation of small area labour force indicators like totals of employed and unemployed people and unemployment rates. Small area estimators of these quantities are derived from four ...
Estudio métrico sobre la actividad investigadora usando el software libre R: el caso del sistema universitario gallego
(Universidad Nacional Autónoma de México, 2017)
[Resumen] Este trabajo representa una nueva alternativa para el estudio, clasificación y comparación de la producción científica de centros de investigación, utilizando las funciones de tratamiento de datos del paquete ...
Small area estimation of average compositions under multivariate nested error regression models
(Springer Science and Business Media Deutschland GmbH, 2023)
[Abstract]: This paper investigates the small area estimation of population averages of unit-level compositional data. The new methodology transforms the compositions into vectors of Rm and assumes that the vectors follow ...
Cooperation on capacitated inventory situations with fixed holding costs
(Elsevier, 2015-03-16)
[Abstract] In this paper we analyze a situation in which several firms deal with inventory problems concerning the same type of product. We consider that each firm uses its limited capacity warehouse for storing purposes ...
Nonparametric estimation of the conditional variance function with correlated errors
(Taylor & Francis, 2006)
Nonparametric forecasting in time series: a comparative study
(Taylor & Francis, 2007)
The problem of predicting a future value of a time series is considered in this
paper. If the series follows a stationary Markov process, this can be done
by nonparametric estimation of the autoregression function. Two ...
Asymptotic properties of Local Polynomial regression with missing data and correlated errors
(2007)
The main objective of this work is the nonparametric estimation of
the regression function with correlated errors when observations are
missing in the response variable. Two nonparametric estimators of
the regression ...
Local Correlation Integral Approach for Anomaly Detection Using Functional Data
(MDPI, 2023-02-06)
[Abstract]: The present work develops a methodology for the detection of outliers in functional data, taking into account both their shape and magnitude. Specifically, the multivariate method of anomaly detection called ...
The bootstrap for testing the equality of two multivariate time series with an application to financial markets
(Elsevier, 2022)
[Abstract]: The problem of testing the equality of the generating processes of two multivariate time series is addressed in this work. To this aim, we construct four tests based on a distance measure between stochastic ...
Prediction of forest fires occurrences with area-level Poisson mixed models
(Academic Press, 2015-05-01)
[Abstract] The number of fires in forest areas of Galicia (north-west of Spain) during the summer period is quite high. Local authorities are interested in analyzing the factors that explain this phenomenon. Poisson ...
