Title: Functions for PPS sampling
Author: Jack G. Gambino <jack.gambino@sympatico.ca>
Maintainer: Jack G. Gambino <jack.gambino@sympatico.ca>
Description: The pps package contains functions to select samples using PPS
(probability proportional to size) sampling. It also includes a function for
stratified simple random sampling, a function to compute joint
inclusion probabilities for Sampford's method of PPS sampling, and a few
utility functions.

Description: Functions to select samples using PPS (probability proportional to size) sampling. The package also includes a function for stratified simple random sampling, a function to compute joint inclusion probabilities for Sampford's method of PPS sampling, and a few utility functions. The user's guide pps-ug.pdf is included in the .../pps/doc directory. The methods are described in standard survey sampling theory books such as Cochran's "Sampling Techniques"; see the user's guide for references.
