Abstract
An anomaly detection method executed by a computer, the anomaly detection method includes identifying, for each of target periods, a prediction value to be a reference for determining whether an anomaly occurs in the target period; identifying a corrected prediction value acquired by correcting the prediction value of a first target period based on the prediction value and a measured values of a second target period before the first target period; setting one of the prediction value and the corrected prediction value corresponding to the first target period as an upper limit value and the other as a lower limit value; and determining whether the anomaly occurs in the first target period by using a reference defined by the upper limit value and the lower limit value.
