1. An apparatus comprising:

  • a memory device having program code stored thereon; and

    at least one processor operatively coupled to the memory device and operable to execute program code stored on the memory device to;

    calculate, for each of a plurality of sensor groups that each include at least two sensors among a plurality of sensors, a degree of outlierness of target data serving as an examination target relative to a reference data distribution of output from the sensor group; and

    estimate at least one sensor among the plurality of sensors to be a source of outlierness, based on a comparison of the degrees of outlierness of the sensor groups that include the at least one sensor to the degrees of outlierness of the sensor groups that lack the at least one sensor.
