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