# S.SI: Simple Random Sampling Without Replacement In TeachingSampling: Selection of Samples and Parameter Estimation in Finite Population

## Description

Draws a simple random sample without replacement of size n from a population of size N

## Usage

 `1` ```S.SI(N, n, e=runif(N)) ```

## Arguments

 `N` Population size `n` Sample size `e` By default, a vector of size N of independent random numbers drawn from the Uniform(0,1)

## Details

The selected sample is drawn according to a selection-rejection (list-sequential) algorithm

## Value

The function returns a vector of size N. Each element of this vector indicates if the unit was selected. Then, if the value of this vector for unit k is zero, the unit k was not selected in the sample; otherwise, the unit was selected in the sample.
