Information processing device, information processing method, and program

An information processing method comprising:

• calculating a prediction error which is a difference between a prediction value which is output obtained when an explanatory variable of subject data is input to a prediction model and an objective variable of the subject data;
• calculating, on a basis of data that can be used for calculating the prediction error, an index for evaluating an amount of contribution of at least one of the explanatory variable of the subject data, the objective variable of the subject data, and the prediction model to the prediction error;
• and
• calculating the amount of contribution on a basis of the prediction error and the index.

A non-transitory computer readable storage medium having stored thereon a program that causes a computer to execute processes of:

• calculating a prediction error which is a difference between a prediction value which is output obtained when an explanatory variable of subject data is input to a prediction model and an objective variable of the subject data;
• calculating, on a basis of data that can be used for calculating the prediction error, an index for evaluating an amount of contribution of at least one of the explanatory variable of the subject data, the objective variable of the subject data, and the prediction model to the prediction error;
• and
• calculating the amount of contribution on a basis of the prediction error and the index.
