Please help me predict the CPC LABEL for this patentPATENT ABSTRACT: Provided are a prediction device, a prediction method, and a computer program, which related to prediction method using Taguchi-method, and which reflect, in addition to a time difference model, trends in changes over time, thus further improving prediction accuracy. For example, the prediction device determines, from signal values stored in a time series and data for each item, whether or not the signal trend of the signal values has periodicity, and if the signal trend has not periodicity, then a signal period is selected on the basis of the most recent signal trend and the MD trend for each item, and Taguchi-method is used on the data for each item and the signal values in the selected signal period, and prediction is carried out.
