1. A computer-implemented method for identifying abnormal behavior of sets of operators, the method comprising:
- observing behaviors of the operators;
separating operators into groupings, each grouping comprising a plurality of operators;
subsequent to the separating, calculating a test statistic for each grouping based on the observed behaviors for the operators in the grouping, the test statistic testing whether all operators behave in a same manner; and
identifying abnormal behavior for one grouping relative to other groupings, based on statistically significant deviations of the test statistic for the one grouping relative to a normative baseline of similarity amongst the other groupings.

12. A computer program product for identifying abnormal behavior of sets of operators, the computer program product stored on a non-transitory computer-readable medium and including instructions that, when loaded into memory, cause a processor to carry out a method comprising:
-
observing behaviors of the operators; separating operators into groupings, each grouping comprising a plurality of operators; subsequent to the separating, calculating a test statistic for each grouping based on the observed behaviors for the operators in the grouping, the test statistic testing whether all operators behave in a same manner; and identifying abnormal behavior for one grouping relative to other groupings, based on statistically significant deviations of the test statistic for the one grouping relative to a normative baseline of similarity amongst the other groupings. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21)
