Review of Progress in Quantitative Nondestructive Evaluation
The most common question asked of a statistician is "How large should my sample be?" In NDE applications, the most common questions asked of a statistician are "How many specimens do I need and what should be the distribution of flaw sizes?" Although some useful general guidelines exist (e.g. in MIK-HDBK-1823) it is possible to use statistical tools to provide more definitive guidelines and to allow comparison among different proposed study plans. One can assess the performance of a proposed POD study plan by obtaining computable expressions for estimation precision. This allows for a quick and easy assessment of tradeoffs and comparison of various alternative plans. We use a signal-response dataset obtained from MIK-HDBK-1823 to illustrate the ideas.
