Abstract: An analysis apparatus comprises: a processor; and a storage device that stores a prediction model that predicts results for contributing factors of a group of events, wherein the processor executes: a prediction error calculation process in which, on the basis of a first prediction value attained by providing the prediction model with a first appearance frequency for contributing factors of a first event among the group of events, and results corresponding to the first appearance frequency, a prediction error of the first prediction value is calculated; and an error factor extraction process in which, on the basis of a correlation between a second appearance frequency for a contributing factor of a second event among the group of events and the prediction error calculated by the prediction error calculation process, an error factor of the prediction error is extracted from among the contributing factors of the first event.
