Measuring Differences Among Probability of Detection Curves

  • Charles Annis
  • Kimberly Erland


Probability of Detection (POD) curves are compared by two statistical methods to quantify system-to-system differences. The first method assesses performance among a group of inspection systems through an adaptation of statistical analysis of variance (ANOVA). The second method uses a chi-squared statistic to test for a difference between two systems. Examples using eddy current data are given for each technique.
