Probability of Detection Estimation for HIT/MISS Data When Detection Cannot Be Attributed to Specific Flaws: An Exploratory Data Analysis

摘要

Several approaches are explored to the estimation of a probability of detection curve when detection results are per "site," but the site contains multiple flaws. Binary regression is used with different candidate explanatory flaw characteristic variables including flaw sizes and number of flaws. A model treating each flaw as an independent opportunity is also introduced. The different approaches are compared and discussed in the context of estimating a POD curve using specific eddy current bolt-hole inspection data.
