This package provides bootstrap algorithms for Finite Population inference, for estimating the variance of the Horvitz–Thompson estimator.
To install the package from CRAN, run the following code in R:
Or, for the development version:
# if not present, install 'devtools' package
install.packages("devtools")
devtools::install_github("rhobis/bootstrapFP")library(bootstrapFP)
### Generate population data ---
N <- 20; n <- 5
x <- rgamma(N, scale=10, shape=5)
y <- abs( 2*x + 3.7*sqrt(x) * rnorm(N) )
pik <- n * x/sum(x)
### Draw a dummy sample ---
s <- sample(N, n)
### Estimate bootstrap variance ---
