Package: geoaddSAE2 Type: Package Title: Geoadditive Small Area Estimation for Area-Level Model Version: 0.1.2 Authors@R: c( person( given = "Amalyah Rizky Khairunnisa", family = "Sutarto", email = "222212489@stis.ac.id", role = c("aut", "cre")), person( given = "Novi Hidayat", family = "Pusponegoro", email = "novie@stis.ac.id", role = c("aut", "ths") ) ) Description: Fits area-level geoadditive small area estimation (SAE) models by extending the Fay-Herriot area-level model with linear, nonlinear, and spatial effects. The Fay-Herriot model is described by Fay and Herriot (1979) . Geoadditive models combine nonlinear covariate effects and spatial variation as described by Kammann and Wand (2003) , while their application to small area estimation is discussed by Pusponegoro et al. (2019) . Nonlinear covariate effects are represented using penalized splines, while spatial effects are represented using a smooth function of geographic coordinates. Models are estimated using restricted maximum likelihood (REML), and mean squared error (MSE) is estimated using a parametric bootstrap. The package also provides comparisons with the Fay-Herriot and spatial Fay-Herriot (SFH) models.
