Polynomial generator for estimation, estimation apparatus, polynomial generation method for estimation, and estimation method

摘要

An estimating polynomial generating device, comprising: an analysis data storing portion for storing analysis data comprising combinations of input parameter data and output parameter data; a function surface storing portion for storing an equation for a function surface that limits the relationship between an input parameter and an output parameter after homothetic conversion; a homothetic conversion equation storing portion for storing homothetic conversion equations for performing homothetic conversion on the input parameter and the output parameter; a homothetic conversion parameter searching portion for searching for and establishing factors for the homothetic conversion equations using the analysis data, the equation for the function surface, and the homothetic conversion equations; and an estimating polynomial calculating portion for calculating an estimating polynomial, for estimating an output parameter value from an input parameter value, by combining the equation for the function surface and the homothetic conversion equations wherein the factors have been established.
