Sample Selection Indicator for With Replacement Sampling Designs
The function returns a matrix of binom(N+m-1)(m) rows and N columns. Creates a matrix of values (0, if the unit does not belongs to a specified sample, 1, if the unit is selected once in the sample; 2, if the unit is selected twice in the sample, etc.) for every possible sample under fixed sample size designs with replacement

The function returns a matrix of binom(N+m-1)(m) rows and N columns. The kth column corresponds to the sample selection indicator, of the kth unit, to a possible sample.
