    • Small area estimation of average compositions under multivariate nested error regression models 

      Esteban, M. Dolores; Lombardía, María José; López Vizcaíno, María Esther; Morales, Domingo; Pérez, Agustín (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 ...

    • Small area estimation of proportions under area-level compositional mixed models 

      Dolores Esteban, María; Lombardía, María José; López Vizcaíno, María Esther; Morales, Domingo; Pérez, Agustín (Springer Nature, 2020-09)
      [Abstract]: This paper introduces area-level compositional mixed models by applying transformations to a multivariate Fay–Herriot model. Small area estimators of the proportions of the categories of a classification variable ...
