Sampling Support for Fixed Size Without Replacement Sampling Designs
Creates a matrix containing every possible sample under fixed sample size designs
Support(N, n, ID=FALSE)
N |
Population size |
n |
Sample size |
ID |
By default FALSE, a vector of values (numeric or string) identifying each unit in the population |
A support is defined as the set of samples such that for any sample in the support, all the permutations of the coordinates of the sample are also in the support
The function returns a matrix of binom(N)(n) rows and n columns. Each row of this matrix corresponds to a possible sample

# Vector U contains the label of a population
U <- c("Yves", "Ken", "Erik", "Sharon", "Leslie")
N <- length(U)
n <- 2
# The support for fixed size without replacement sampling designs
# Under this context, there are ten (10) possibles samples
Support(N,n)
# The same support, but labeled
Support(N,n,ID=U)
# y is the variable of interest
y<-c(32,34,46,89,35)
# The following output is very useful when checking
# the design-unbiasedness of an estimator
