Abstract
This invention provides an information processing device and information processing program capable of further improving the accuracy of the estimation of the target variable. [Solution] The information processing device 10 includes an acquisition unit 24 that acquires a set of variable values 54 corresponding to a plurality of explanatory variables used for estimation, and an estimation unit 28 that performs a first estimation process which estimates a single target variable from the set of variable values 54 using a simple linear regression model for each explanatory variable and obtains a set of intermediate values 56 which is a collection of provisional estimates of the target variable, and a second estimation process which estimates the target variable using the set of intermediate values 56 and obtains an estimated value 58 of the target variable.
