Design of two-step imaginary Experiment based on Stratification

Abstract

Imaginary experiment is practiced in order to find the optimum solution based on panel evaluation by using virtual product expressed by combination of specification. When we analyze the data obtained in the virtual experiment, it is necessary to take into consideration the goods attribute that constitutes the object evaluated by the panel, and the panel attribute.About the goods attribute, it is desirable to treat many variables.The 2 stage virtual experiment is proposed as a method for it. About the panel attribute, stratification is required. In this paper, we show the 2 stage virtual experiment based on stratification.
