Application of EXCEL in Fitting of Tobacco Purchasing Risk Occurrence Curve
摘要
Abstract
To effectively control the risk in flue-cured tobacco purchasing and extend purchasing process management method,the curve representing tobacco purchasing risk was plotted by the aid of EXCEL.The results showed that the relationship between variables x (purchasing weeks) and y (purchasing risk index of weeks) could be represented by a parabolic curve.Higher degree polynomial curves were tested,it was found that the 3rd-degree polynomial curve was of high fitting precision and simple in calculation,which was more suitable for the establishment of mathematical model of purchasing risk.关键词
