<p>Provided are a prediction device, a prediction method, and a prediction program having a high prediction accuracy in prediction of a prediction object varying time-dependently. In the prediction of the prediction object, a change of the prediction object is predicted on the basis of data concerning a plurality of items related to the prediction object. That is, for each item, a factorial effect value is derived that represents the SN ratio of the prediction object to each data including the data of the item relative to the SN ratio of the prediction object to each data excluding the data of the item. Then, the strength of the SN ratio of the comprehensive estimated value to the data of a plurality of items selected in descending order of the derived factorial effect value is calculated for each value of the number of items. Then, on the basis of the SN ratio of the comprehensive estimated value calculated for each value of the number of items, the number of items is determined. Then, in descending order of the derived factorial effect value, items in the determined number of items are selected. Then, on the basis of the data of the selected items, a change of the prediction object is predicted by using a method such as a T-method.</p> |
