    • An alternative analysis of variance 

      Longford, Nicholas T. (Institut d'Estadística de Catalunya, 2008)
      Article
      Open Access
      The one-way analysis of variance is a staple of elementary statistics courses. The hypothesis test of homogeneity of the means encourages the use of the selected-model based estimators which are usually assessed without ...
    • Assessing influence in survival data with a cure fraction and covariates 

      Ortega, Edwin M. M.; Cancho, Vicente G.; Lachos, Victor Hugo (Institut d'Estadística de Catalunya, 2008)
      Article
      Open Access
      Diagnostic methods have been an important tool in regression analysis to detect anomalies, such as departures from error assumptions and the presence of outliers and influential observations with the fitted models. Assuming ...
    • Estimating unemployment in very small areas 

      Ugarte, Maria Dolores; Goicoa, T.; Militino, Ana F.; Sagaseta-López, M. (Institut d'Estadística de Catalunya, 2009)
      Article
      Open Access
      In the last few years, European countries have shown a deep interest in applying small area techniques to produce reliable estimates at county level. However, the specificity of every European country and the heterogeneity ...
    • On the performance of small-area estimators: fixed vs. random area parameters 

      Costa, Àlex; Satorra, A.; Ventura, Eva (Institut d'Estadística de Catalunya, 2009)
      Article
      Open Access
      Most methods for small-area estimation are based on composite estimators derived from designor model-based methods. A composite estimator is a linear combination of a direct and an indirect estimator with weights that ...

    • Sampling design variance estimation of small area estimators in the Spanish Labour Force Survey 

      Herrador, M.; Morales, Domingo; Esteban, M. D.; Sánchez, Ángel; Santamaría Arana, Laureano; Marhuenda, Y.; Pérez, A. (Institut d'Estadística de Catalunya, 2008)
      Article
      Open Access
      The main goal of this paper is to Investigate how to estimate sampling design variances of modelbased and model-assisted small area estimators in a complex survey sampling setup. For this purpose the Spanish Labour Force ...
