Support {TeachingSampling} | R Documentation |
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
