Icarus (Icarus Calibrates And Reweights Units in Samples) is an R package providing useful functions for calibration and reweighting estimators in survey sampling. The former name of this package was gaston.
To cite Icarus in publications use: Rebecq, Antoine (2017). Icarus: an R package for calibration in survey sampling. R package version 0.3.0.
You can use the following instruction to install icarus (from CRAN):
install.packages("icarus")
However, if you wish to install the latest version of icarus, you can use devtools and install directly from this github repo:
install.packages("devtools")
library(devtools)
install_github("haroine/icarus")
````
## Short example
In this example, we perform calibration (with the "raking" method) on the test dataset _data_employees_ included in icarus:
library(icarus)
N <- 300 ## Population size
weightedMean(data_employees$movies, data_employees$weight, N)
mar1 <- c("category",3,80,90,60) mar2 <- c("sex",2,140,90,0) mar3 <- c("department",2,100,130,0) mar4 <- c("salary", 0, 470000,0,0) margins <- rbind(mar1, mar2, mar3, mar4)
wCal <- calibration(data=data_employees, marginMatrix=margins, colWeights="weight" , method="raking", description=FALSE)
weightedMean(data_employees$movies, wCal, N) ```
