The Fay-Herriot model is described by Fay and Herriot (1979) <doi:10.1080/01621459.1979.10482505>. Geoadditive models combine nonlinear covariate effects and spatial variation as described by Kammann and Wand (2003) <doi:10.1111/1467-9876.00385>, while their application to small area estimation is discussed by Pusponegoro et al. (2019) <doi:10.21108/JDSA.2019.2.15>. 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.https://github.com/r-universe/amlyhrzky/actions/runs/38823514330Thu, 15 Oct 2026 19:20:02 GMTgeoaddSAE20.1.2successhttps://amlyhrzky.r-universe.devhttps://github.com/cran/geoaddSAE2geoaddSAE2-intro.RmdgeoaddSAE2-intro.htmlIntroduction to geoaddSAE22026-09-30 13:55:312026-10-15 19:20:02
