In the past, to analyze statistical data with a multiple regression analysis, a stepwise method by computer which improves an intermediate regression equation step by step, or an interactive method by human experts which omits some intermediate calculations just to suit the occasion has been used. If any features of the data are changed by market trends or commercial media, it is difficult to get adequate results in practical length of time by these methods. Therefore, this paper proposes an analysis method in which first a rule-base of an expert system which is constructed by eliciting the knowledge of expert analysts to get an intermediate regression equation and then the expert analysts improve the equation interactively. The effects of this method are clarified in using it to derive a sales forecast equation for apparel goods
