IkRS: Sample Membership Indicator for Random Size sampling designs

Description

Creates a matrix of values (0, if the unit belongs to a specified sample and 1, otherwise) for every possible sample under random sample size designs without replacement

Usage

IkRS(N)

Arguments

N

Population size

Value

The function returns a matrix of \(2^N\) rows and \(N\) columns. The \(k\)th column corresponds to the sample membership indicator, of the \(k\)th unit, to a possible sample.
