1-Stage Freedom analysis
Use these utilities to assist with planing and analysis of simple 1-stage surveys to demonstrate
disease freedom. Methods are appropriate for sampling units (animals, fish, plants, etc) to demonstrate cluster
(herd, flock, farm, tank, etc) freedom, or for either individuals or clusters to demonstrate
population freedom. All methods assume representative sampling of units from the population and methods are
included for large (or unknown) and finite (known) population size. Most of the options (except where noted)
assume perfect (100%) test specificity.
