Inverse sampling: a composite approach

Abstract

This article describes a two-stage composite sampling scheme to locate a fixed number of rare items in a sample. A recursion formula is developed to compute the expected costs associated with this sampling scheme. The two-stage scheme is shown to be cost effective when compared with the traditional method of individual testing.

Keywords:

• Composite sampling
• Inverse sampling
