A Program of Two-error Standard Curve Regression Based on a Continuous Propagation Model of Uncertainty
-
摘要: "不确定度连续传递模型"是建立在"约克方程"基础上的双误差标准曲线回归新理论。文章简单介绍了这一理论的基本思路与数学模型以及根据该模型设计出的计算机程序。该程序可进行标准曲线的一次曲线、二次曲线、三次曲线、指数曲线和对数曲线的简单回归、一次曲线的Y-单误差(含相对误差和绝对误差)回归,一次曲线x、y双误差(含相对误差和绝对误差)回归,并可根据回归曲线计算出给定允许最大误差时的检出限。程序功能齐全、界面友好、使用方便,是化学检测实验室必备的工具软件之一。Abstract: This continuous propagation model of uncertainty is a new two-error standard curve regression theory, which is based on "York's algorithm". A brief introduction of the basic idea of the theory, mathematical model, and computer program, which is in accordance with the model is discussed in this paper. The program can perform simple standard curve straight line, quadratic curve, cubic curve, exponential curve, logarithmic curve; Y-single-error and x, y two-error (containing relative and absolute error) regression for standard curves. Moreover, detection limit can be calculated in terms of regression curve when given the allowed maximum error. This program is complete in function, friendly in interface and convenient in use, and is one of necessary tool softwares in chemical testing laboratory.
