Title: Transformations for Unit-Level Small Area Models
Version: 1.0.2
Author: Nora Würz [aut]
Maintainer: Nora Würz <nora.wuerz@uni-bamberg.de>
Description: The aim of this package is to offer new methodology for
        unit-level small area models under transformations and limited
        population auxiliary information. In addition to this new
        methodology, the widely used nested error regression model
        without transformations (see "An Error-Components Model for
        Prediction of County Crop Areas Using Survey and Satellite
        Data" by Battese, Harter and Fuller (1988)
        <doi:10.1080/01621459.1988.10478561>) and its well-known
        uncertainty estimate (see "The estimation of the mean squared
        error of small-area estimators" by Prasad and Rao (1990)
        <doi:10.1080/01621459.1995.10476570>) are provided. In this
        package, the log transformation and the data-driven log-shift
        transformation are provided. If a transformation is selected,
        an appropriate method is chosen depending on the respective
        input of the population data: Individual population data (see
        "Empirical best prediction under a nested error model with log
        transformation" by Molina and Martín (2018)
        <doi:10.1214/17-aos1608>) but also aggregated population data
        (see "Estimating regional income indicators under
        transformations and access to limited population auxiliary
        information" by Würz, Schmid and Tzavidis <unpublished>) can be
        entered. Especially under limited data access, new
        methodologies are provided in saeTrafo. Several options are
        available to assess the used model and to judge, present and
        export its results. For a detailed description of the package
        and the methods used see the corresponding vignette.
