Title:
ANALYSIS DEVICE, ANALYSIS METHOD, AND ANALYSIS PROGRAM
Document Type and Number:
WIPO Patent Application WO/2019/163160
Kind Code:
A1
Abstract:
Provided is an analysis device comprising a processor and a storage device for storing a forecast model formula for forecasting a result with regard to factors of a group of events. The processor executes: a forecast error computation process for computing, on the basis of a first forecast value obtained by applying to the forecast model formula a first frequency of occurrence with regard to factors of a first event from among the group of events and a result associated with the first frequency of occurrence, a forecast error of the first forecast value; and an error factor extraction process for extracting an error factor of the forecast error from among the factors of the first event on the basis of a correlation between a second frequency of occurrence with regard to factors of a second event from among the group of events and the forecast error computed by the forecast error computation process.
