S.piPS: Probability Proportional to Size Sampling Without Replacement In TeachingSampling: Selection of Samples and Parameter Estimation in Finite Population

Description

Draws a probability proportional to size sample without replacement of size n from a population of size N.

Usage

 `1` ```S.piPS(n, x, e) ```

Arguments

 `x` Vector of auxiliary information for each unit in the population `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 the Sunter method (sequential-list procedure)

Value

The function returns a matrix of m rows and two columns. Each element of the first column indicates the unit that was selected. Each element of the second column indicates the selection probability of this unit
