Statistical Analysis of Hit/Miss Data (Preprint)
Abstract
There has been renewed interest in the analysis of Hit/Miss or Bernoulli data in the context of Nondestructive Evaluation (NDE). Many contributions have been made with a focus on confidence bound estimation on this type of data. Some concern regarding the proper calculation and use of a90 and a90/95 estimates has been raised. In particular, the behavior of a Probability of Detection (POD) curve for large flaw sizes above stated a90 estimates has been of concern. This paper will give a brief historical overview of the analysis of hit/miss data, and propose a remedy regarding recent concerns. The end result will be a procedure that helps avoid pitfalls in the analysis of hit/miss data.
