DATA PREDICTION METHOD AND DATA PREDICTION SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a data prediction method and system to understand a prediction process by using a prediction model for realizing highly precise prediction.

SOLUTION: A prediction model 4 is constituted of a prediction model A for outputting a prediction value concerning the featured values of a date for prediction and a prediction model B including a prediction value outputted by the prediction model A in an input factor for outputting the prediction value in each predetermined time on the date for prediction. The prediction model 4 is constructed by using the latest result data and the past result data, and a prediction value is obtained by inputting input data for prediction to the prediction model 4. Then, a prediction error/model error are calculated from the latest result data and the prediction value, and a corrected prediction value is obtained on the basis of the prediction error/model error.
