Two-stage sampling in pharmaceutical applications.

Journal Article

In the pharmaceutical industry, some tests for quality assurance before, during and after the manufacture of a drug product involve a two-stage sampling technique. We propose statistical testing procedures in a two-stage sampling problem with large within-class sample sizes. We also derive a two-stage sampling plan by minimizing the expected squared volume (or the generalized variance) of the confidence region related to the test. We present two examples to illustrate the proposed methods.
