Abstract: Prediction of time series data can be performed while coping with a “non-equidistant event,” “extrapolation,” and a “base line shift.” An event regression section calculates event prediction data that is predicted values of metric data in an intended period including a past certain period on the basis of actual measured value data indicating values of the metric data in the past metric data. A correction section calculates, as prediction result data that is a prediction result of the time series data, data obtained by shifting each value of the event prediction data in response to a difference between the actual measured value data and the event prediction data in a same period.
