To provide a systematic method for specifying the formula of a utility function that can handle inferior goods and inelastic goods, which is difficult in the prior art, and generating the specified formula from observation data.SOLUTION: A method uses an implicit function based on an addition structure of a utility function, while adopting an expression that allows the value of the implicit function to be calculated reliably by a computer; strives to minimize the parameters of the function; tries to keep it simple; and increases the success rate of regression by decomposing multivariable non-linear multiple regression into n non-linear simple regressions.SELECTED DRAWING: None 【課題】先行技術では困難であった下級財と非弾力的な財を扱える効用関数の数式を特定化し、その特定化された数式を観察データから生成するシステマティックな方法を提供する。【解決手段】方法は、効用関数を足し算構造を基本とする陰関数としつつ，陰関数の値は計算機では確実に計算できるような式を採用し、関数のパラメータを最小限にするよう努力し，シンプルを心がけ、多変数の非線形の重回帰を，ｎ回の非線形の単回帰に分解する方法により，回帰の成功率を高める。【選択図】なし
