Abstract: Disclosed is method for estimating statistical distribution characteristics of product parameters. The method comprises determining n number of product parameters, which characterize a product, and m number of characteristic parameters dependent on the product parameters, determining m number of correlation functions that represent the characteristic parameters in terms of the product parameters, and obtaining inverse functions of the correlation functions that represent the product parameters in terms of the characteristic parameters. After fabricating test products to empirically determine quantitative relations between the product and characteristic parameters, the method includes measuring k number of test products and preparing measured data of the characteristic parameters.
