Abstract: An inference unit (1033) predicts as a prediction parameter value, a future parameter value of a time synchronization parameter used for time synchronization calculation which is calculation for synchronizing times of two devices. When a measured parameter value which is a measured value corresponding to the prediction parameter value is generated with elapse of time, a cumulative distribution table generation unit (1034) calculates as a prediction error, a difference between the measured parameter value and the prediction value. A cumulative probability calculation unit (1036) calculates an abnormality degree indicating possibility that an abnormality is included in the measured parameter value, using the prediction error.
