摘要
分析了物质浓度与颜色读数关系类型。借助SPSS软件对所给数据进行因子分析,又利用散点图大致确立了二者的关系类型,即回归分析模型。利用Matlab进一步确立了完全二次(quadratic)回归模型并求出回归系数得到回归分析方程。通过计算误差的标准差以及将拟合数据与现有数据进行对比的折线图验证了该模型的合理性。
In this paper, the relation type between matter concentration and color reading is analyzed. Factor analysis of the given data is conducted by SPSS software and scatter plot. Thus, the relation type between them is roughly established, that is regression analysis model. The quadratic regression model is further established by using MATLAB, and the regression coefficient is obtained to obtain the regression analysis equation. The rationality of the model is verified by calculating the error of the standard deviation and the line chart of comparing the fitting data with the existing data.
