geoSAE

This function is an extension of the Small Area Estimation (SAE) model. Geoadditive Small Area Model is a combination of the geoadditive model with the Small Area Estimation (SAE) model, by adding geospatial information to the SAE model.

Example

library(geoSAE)

#Load the dataset for unit level
data(dataUnit)

#Load the dataset for spline-2
data(zspline)

#Load the dataset for area level
data(dataArea)

#Construct the data frame
y       <- dataUnit$y
x1      <- dataUnit$x1
x2      <- dataUnit$x2
x3      <- dataUnit$x3
formula <- y~x1+x2+x3
zspline <- as.matrix(zspline[,1:10])
dom     <- dataUnit$area
xmean   <- cbind(1,dataArea[,2:4])
zmean   <- dataArea[,5:14]
number  <- dataUnit$number
area    <- dataUnit$area
data    <- data.frame(number, area, y, x1, x2, x3)

#Estimate EBLUP
eblup_geosae <- eblupgeo(formula, zspline, dom, xmean, zmean, data)
eblup_geosae$eblup

#Estimate MSE
mse_geosae <- pbmsegeo(formula,zspline,dom,xmean,zmean,data,B=100)
mse_geosae$mse

## eblup_geosae$eblup        #to see the result of EBLUPs with Geoadditive Small Area Model each area
## mse_geosae$mse            #to see the result of MSE with Geoadditive Small Area Model each area
